In the output ecc queue record, the source value is truncated at 120 chars. Note that the parameters in payload have "source" parameter with the complete URL.
Steps to Reproduce
If you need to use the ecc_queue topic/source values, ensure that the endpoints are no longer than 120 characters.
Note that if the endpoint is longer than 120 characters, it will be truncated. Ensure that the data is sent on the actual payload and avoid using the URL.
Issue fixed in Istanbul for REST and SOAP. SOAP executeAsync still has problem but wont be fixed as executeAsync in SOAP is legacy and behaves similar to execute. Use execute() instead
