how did you open the terminal in 09:34??? please do help me

[@sekhniashvili]

Hey man, Nice and helpful video. Thank you. I get Forbidden error when sending message from socket client {"message": "Forbidden", "connectionId":"some_ID", "requestId":"some_ID"} I think I have not missed any step. The request does not appear in lambda logs, so I think API gateway blocks the request for some reason.

[@AbhishekKumar-wx3dh]

How do you handle error from the lambda fn. Error which can come from not connecting to db.

[@isohumulone]

Where is the array variable "ids" initialized.

Great video! How can I make the web app hosted completely on cloud, without having to use the terminal/local host?

[@fedelecavaliere5249]

Very nice! But I was questioning if using Lambda what it's billed to me it's per say 100ms for each client for every message. On the other hand Lambda is taking up and storing my variables with my ids... How does Lambda bills me? Thank you!

[@smritieligar2518]

i am getting Unexpected server response: 502 when i run wscat(9:38 timeline in the video). how do i solve it?

Yea I'm too facing the same issues ! Can you please tell me what to do next? If you resolved..

[@eruiluvatar6178]

One question, what about pricing? Can we use this solution for a high load system?

[@CATAPASMARENT]

When i send a message i always go in the $default routeKey any advice or code sample ?

[@swethareddy8550]

Thank you

[@edilsonfb]

Thank you for the video, it really helped me! I've facing an issue regarding using only serverless.yml to deploy the application. Locally everything works, but on aws the postToConnection only send if a user has joined. I'm saving the data in mongogb. Is there a huge difference by doing the firsts steps in the video and doing locally?

[@oldyoung]

The message store in dynamodb ?

why should we use .promise() when we are using async and await

[@mcpoppyborger]

I’m getting an unexpected serverr response: 502 :

[@peppyday]

any solution

[@BiteSizeAcademy]

Try to check the logs of the lambda function to see what causes the error, then troubleshoot it: aws.amazon.com/premiumsupport/knowledge-center/lambda-troubleshoot-invoke-error-502-500/

any idea how to store the chat message in dynamodb ( need schema )

[@Jagadish47]

HOW lambda holds the names object ( var names = { }; ) for every request won't it become resetted ???

[@DuffMan]

If anyone is trying this lately, I don't know if something changed in AWS, but I was getting bad gateway from the wscat connection. So I checked cloudwatch and it was giving me this error: Error: Cannot find module 'aws-sdk'". So I installed @aws-sdk/client-apigatewaymanagementapi directly and it fixed the issue. Usage: import { ApiGatewayManagementApiClient, PostToConnectionCommand, } from '@aws-sdk/client-apigatewaymanagementapi' const command = new PostToConnectionCommand({ ConnectionId: id, Data: Buffer.from(JSON.stringify(body)), }) return await client.send(command)

[@Neosdragon]

Can you further elaborate on this?
