Unable to Upload Application Snapshot using REST API payloads across EDM environments

Issue with Application Snapshot migration using REST API - Our client has a DR environment setup wherein the Application Snapshot is downloaded from one of the EDMCS instance and then uploaded to the other EDMCS instance using REST API payloads. We are following the migration steps mentioned in the following Oracle document.

Out the steps mentioned here, the first step of POST method is working fine. However, while executing the second step based on what is suggested in this Oracle documentation linked here - - we are getting the error response as:
{"details":"bytes lost during upload","status":1,"links":[{"href":"**instance name**/interop/rest/v2/files/upload/64342174122862050","action":"PATCH","rel":"self","data":null}]}
