Hi @remiwaw The stack trace is hardly readable. Kindly format it from next time before posting

[rahul-lohra]

I reviewed the logs but couldn’t identify a clear indication of what went wrong.

There are multiple ways a call can be terminated—such as call.leave(), call.reject(), or call.end().
I’d suggest adding a breakpoint to see which of these methods is actually being invoked and then backtracking to identify what triggers it.

Ok thanks, will do.
