UiPath Tutorial | Deep Understanding Of Application Exception in Uipath

🔥 Subscribe for uipath tutorial videos
: We will a deep understanding of application exception in uipath. in this demo we will learn about how the application exception o curs in Uipath and what is an application exception. In general sense the application exception is the one where the application fails or freezes upon which uipath can not process the data. This exact state is called application exception phase in uipath.
Application exception is part of set transaction status in uipath. This is the 3rd block which contains workflow to close the application and retry the transaction item from the queue. In this you tube tutorial we are going to learn how to utilise the application exception in uipath.
At the time of application exception in uipath the catch section of processing state captures the exception or error. Next the finally section of the try catch block is comes into play. This is where we find the set transaction status.
Application exception in uipath is an integral part of any project. Having a deep understanding of the system and designing the workflow accordingly does a great deal.
Application exception in uipath concentrates on retry mechanism. How a new transaction item is recreated post application exception is shown in this youtube video. Please do subscribe to expohub and connect to the stream of uipath experts.

60th like.. Undoubtedly Excellent piece of work. If possible Do a session on use case with Exception Handling mechanisam That includes try catch,Retry,,Throw, Rethrow activities.This is the area where most people facing difficulty during interw. Thank you.

[@AutomatewithRakesh]

Thank you for everything

[@ajishjoy3778]

Great explanation .. it would be nice if you can explain more on how the queue item which was set to failed will again get retried after processing all other transaction items. How get transaction data gets that particular failed item and process it again

[@jeremyheng8573]

This is very helpful! I had finished entire RE Framework series. Thank you!

[@samaddy1643]

This is the most detailed and useful explanation of REFramework I have ever seen anywhere. Even better than the explanation in Uipath Academy.

[@echonow5157]

Great Explanation!! Can you please make a video on How to retry from only failed part of application, instead of retrying from the beginning of the application? Frame work is retrying all the steps from the beginning..

[@kelip182]

The 'Retry' set in Orchestrator example / demo is easy to understand. And the App error simulated is well explained too. Thanks Rakesh!

[@reshmakp6423]

Hi Rakesh, please give a explanation with demo for RE framework without using orchestrator, i.e with usage of datarow. It would be helpful

[@AutomatewithRakesh]

Sure Reshma

Hi Rakesh I hope you are doing well. My humble request to you please create the sample projects with RE Framework templet, and we need to clear more how to handle the exceptions, and we need to know how did you implemented this workflow.

[@HP.0]

If a system exception occurred in the ‘Process Transaction’ state, What steps are followed? "Set Transaction Status" ---->Invoke “RetryCurrentTransaction.xaml” --> Invoke “TakeScreenshot.xaml” --> Invoke “CloseAllApplication.xaml” --> Get next available transaction item. Are the above steps correct? Could you please confirm?

[@pravinbindage]

Very Informative Video

Thank you Pravin, Continue your learning journey and keep commenting!

[@ashishkumargiri95]

Hello Rakesh.. It was a very nice video. Thank you for that. Can you make a video specific to Retry Current Transaction xaml file. I have few queries on that retry part, 1: How can set retry to 3 2: While creating queue, we can set retry and in config as well. If we define both of them then which value will be taken? 4: Need detailed explanation on Retry current transaction, how its mechanism works? 3: When we set transaction to failed with Error type application exception then automatically same queue item is set as retried and anothor queue item is added. Is my understanding correct? Requesting to check my concern and ket me know the details Thank you in advance.

[@amanrawat6656]

Thank you so much sir

[@John-io1zu]

Great work, Easy way to understand.

[@AutomatewithRakesh]

Thank you

[@sparshsinha4778]

Hi sir, you mentioned that the transaction item that failed due to application exception will be retried, but in the retry robot flowchart, it directly goes to noretry block as Maxretry is set to 0 in the config file for queue implementation and it incremented the transaction number also. So how does it retry the same transaction item as if it goes to the get transaction block, will it not point to the same transaction item which threw application exception in the first place. Or autoretry is inherent property of queues itself because of which same item will be fetched when it has an application exception for the maxretries no. set in the queue.

[@sparshsinha4778]

Please reply for sure, it will clear my doubt.

[@HP.0]

MaxRetryNumber is used from Config when NOT using orchestrator. Max # retries is used from the Queue setting in Orchestrator when using Queues.

Hi Rakesh, Just a gentle follow up on the below comment and one more question - How to handle a random popup which may appear anywhere anytime in the application ? Thanks in advance !! Suprit

[@AutomatewithRakesh]

There are multiple was to handle such popups. 1. Try Catch Block 2. you can develop a pop up handler workflow after each and every activity to check if there is a pop up on the screen and close it or take action 3. Parallel activity paring with element exists on screen etc... This is matter of pure logic to be developed for each individual project and can not be confined. As we develop the project we need to adapt changes to handle such pop ups.

[@jagirapuvishwateja6258]

very good explanation brother.thank you.

[@rahem747]

Mr. Rakesh, your lectures on uipath are very good. I've seen almost all but I want to know how to convert pdf files to excel please guide, regards

[@AutomatewithRakesh]

Hi Khan, thank you, appreciate your encouragement! You can use this link where we have demonstrated how to extract data from PDF to Excel! kzbin.info/www/bejne/e3bPi5mpoZabrJo

[@AutomatewithRakesh]

In case if you are looking to convert complete PDF file to Excel, then you need to design the workflow using send hot keys and use the available options in PDF to Export PDF(convert to word, excel etc) to Excel or any other available apps.

[@supritpradhan6655]

Hi Rakesh, Could you make a video on the below interview questions that are frequently asked, if you could give few sample examples that will be great help 1] What kind of challenges you have faced while developing the bot. 2] What kind of issues do you get in production and how you resolve it? Thanks in advance !!

Its really helpful video i just have one question if the process got fail how its re try shall I write any code or and where bot get data to process the data

[@AutomatewithRakesh]

On the event of application exception the Reframework is designed to go to init block and re-initiate all the required application and the process.I have shown it in the video if you completely go through the video you should get it

[@AutomatewithRakesh]

Kindly let me know in case you still unable to find it

Another question is as i saw you business rule exception you are using throw activity but in system exception you are not using any thorw activity so how could write log in log file and what is use of terminate workflow

[@AutomatewithRakesh]

To understand all of these you can start watching all the videos of ReFramework as all the videos are made in sequential manner and I have covered all minor details

Hi Rakesh, Since I did not find the moving data from PDFextract to Processed sheet part on the video, I tried to do it myself, but ended up statically use "Delete Range" , I am curious to know if it is possible to find index of say last cell with value and use that to clear range. so that it will be more dynamic. Thanks in Advance!!.

[@ankitachatterjee2111]

Sir you mentioned that in the Robot retry flowchart it will go to the no retry block when using orchestrator , but in the demo i saw the exact opposite thing happening ..the second entry got retried at the end which should'nt have been the case since maxretry number was 0 ... and also i want to understand why was the excel getting closed and opened all the time even for successful transactions?sir please reply .... it's very urgent

Hi Ankita recently I have created another video around Max retry please do watch you will get much better clarity

[@yerriboyinalokesh2488]

Wow..that's a great explanation.

[@AutomatewithRakesh]

Glad it was helpful!

[@ponnanikhil9611]

Great. One doubt. While creating Queue we have given retry number for transaction item. Where would we have given retry number in case of system exception occurs(browser crush..etc). Little confuse.

[@HP.0]

If System Exception happen that mean transaction item failed and hence the Max # of retires is followed from Orchestrator in case of Queue or MaxRetryNumber is followed from Config if Orchestrator is not being used. I am learning as well but this is my understanding.

[@SyedAli-iq4ku]

Thank you Rakesh

Hi Rakesh, I encountered the below qns. Is the below sequence of event correct? for your advise. Thks Qns: If a system exception occurred in the ‘Process Transaction’ state, list down the events that happens in sequence. Ans: Invoke “RetryCurrentTransaction.xaml” --> Invoke “TakeScreenshot.xaml” --> Invoke “CloseAllApplication.xaml” --> Get next available transaction item

Hi Rakesh, I got one doubt at 17:52 min you just showed status as 'Failed' but in the queue why was the status being reflected as 'Retried'. I am slightly confused and not sure where I missed the point. Thank you in advance if you can clarification.

[@crazyvenky1258]

Retry can be happened when only transaction item has been failed so the status has been set to failed.

When I get system exception queue is getting added up with 5 more transactions...how to over come that and @what stage ur moving the input sheet(pdfextract) data to processed sheet in Excel and how ru deleting data in sheet1(pdfextract)?

[@AutomatewithRakesh]

Hi there, if the data is getting added multiple times, that means you need to create a separate dispatch sequence xaml to run once do not add in the init block as anytime there is system exception it will come to init block and execute the activity which you have written to upload data to queue. Hence keep it separate. I have specific videos on dispatcher and performer bots. Next the writing of data in excel should be done in the process transaction state
