Hello,

I am trying to invoke a functionApp from a logicApp, but I am experiencing strange behavior.
If I am directly passing a created JSON with data, then it's working correctly, but If I am trying to create a body in the functionApp, getting InternalServerError.

Working when passing created body with data as shown below:

It's resolved after checking the FunctionApp logs.
A number value is getting passed instead of Integer in one of the field which is causing issue, so explicitly converted that number value to Int and then passed it to functionApp and it worked.

@PranavGupta-6411 ,

Thanks for providing the answer and helping the community. Just to add to this, in case you are encountering 503 service unavailable at the Functions level, you can explore the Diagnose and Solve problems section in the Functions portal and run the "Function app down or reporting" detector. It will provide insights about downtime,exceptions and performance.
