Review Comment:
Yes, server retrurned exception message clearly states that MD5 Hash does
not match.
Example:
Operation failed: "The MD5 value specified in the request did not match with
the MD5 value calculated by the server.", 400, PUT, _URL_, Md5Mismatch, "The
MD5 value specified in the request did not match with the MD5 value calculated
by the server. RequestId: _rid_ Time:2023-09-21T08:33:25.6135970Z"
But if an invalid MD5 Hash is sent (Which does not represent any data),
server message will be:
Operation failed: "The value for one of the HTTP headers is not in the
correct format.", 400, PUT, _URL_, InvalidHeaderValue, "The value for one of
the HTTP headers is not in the correct format. RequestId: _rId_
Time:2023-09-21T08:35:29.2777203Z"
