Hello Nivedipa-MSFT - Thanks for the response.
It's a reply. I verified on my end that endpoint (I posted incorrect endpoint) and message-id are correct.
Could you please let us know in what scenario this leads to a ColdStoreNotSupportedForMessageException, and if there is any documentation related to the required internal parameters (cutOffColdStoreEpoch)?
I believe this could be a backend issue or an edge case, as the same code has been running for quite some time without any issues. Please refer to the information in error response attached in above post for the request ID and timestamp for further investigation.
