Hi Rav - I submitted this file 2 weeks ago and went back in today to check on the progress and saw this error message. Previously it was giving me the error message "The requestId is valid, but the pull request is yet to be queued"
Similar to Leanne we have the error message after we have uploaded the STP file and have received the following error - "ATO sent the poll response but the service failed to deserialize it". This was 3 weeks ago and the error is still there with the ATO receipt no . Other payruns have successfully uploaded though we do have one still pending as well.
