Hello Nivedipa-MSFT - Thanks for the response.
It's a reply message. I checked on my side that endpoint and message-id is correct.
Could you please let us know in what scenario that lead to ColdStoreNotSupportedForMessageException and any documentation related to the required internal parameter (cutOffColdStoreEpoch)?
I think it could be a backend issue or an edge case since the same code has been running for quite some time without any issues. Please refer to attached error response for the request ID and timestamp for further investigation.
