I built the NAR for version 1.9.2 (which we are currently running). I have built a similar flow as I did when we discovered the bug. PutSQS from your PR works like a charm. The PutSQS processor in current master would have reported success on both processors (image) because the batch message was OK.

@ep-mo Thanks for your feedback and for the test flow.

The code looks fine. I ran some test flows for both PutSQS and DeleteSQS.
Merging to master.

@pvillard31 Thanks for fixing the issue.
