Azure function IoTHub device connection state message decode error

Question

I've a route to forward Azure IoTHub device connection state messages to service bus queue.
On that queue I'm triggering Python function using v2 programming model.

Looks like the trigger is not being decoded properly. Here is the error,

Result: Failure Exception: ValueError: cannot convert value of field 'SequenceNumber' in trigger metadata into int: invalid literal for int() with base 10: '000000000000000001dummy100000004000000000000000000

Answer 1

This is a python error. You need to check if you input string contains characters that are not valid digits for a base 10 number. See simple explanation here: https://www.geeksforgeeks.org/how-to-fix-valueerror-invalid-literal-for-int-with-base-10-in-python/
