Duplicate message because of 500 error

Hi All,

I've got an issue with a new partner where they send the same message twice, because they receive a HTTP 500 error.
However i cannot find this 500 error on our server. I do see in the logging that we receive the 2nd (duplicate) message right before pyas2 was able the send a succesfull MDN back. It tries to process the dupilcate but fails and the parnters receives a failed MDN.

Anyone seen this behaviour before?
Here's the debug log for this issue.

I did find the issue.
pyas2 didn't had the right permissions to save the payload. after changing that it went just fine.
Would have been nice to find that somewhere in the logging:)

Thanks,
Hans
