Hi Sravan, Could you please explain why can't we call a sub flow using the lookup function.

[@RAJANSINGH-bc5xz]

same doubt

[@karshak]

If we use the lookup function To fetch the value based on key, when key not available, getting the error in private flow as key not available, but in the dataweave is giving mule expression error

[@neelamchhipa5625]

Can you help me in how to test lookup functionality using mUnit test case

[@MuleSoftTechZone]

U don't have to specially mock lookup. As it's part of Dataweave. If your lookup is calling a private flow that has database operation, then mock that database with test data. That's it

@@MuleSoftTechZone I am getting Error relatee unable to find flow used in lookup

[@neelamchhipa5625]

Tried with simple flows not having any Database calls but getting this error whereas the same code is working fine when testing directly
