  Validate File Content: Open the file in a text editor to verify that the first line is indeed a session header record. It should typically start with a specific identifier that indicates it is a Type 0 record.

  Use Correct File Type: Make sure you are using the correct file type for the upload process. If you are using a tool or program to generate the file, check its settings to ensure it is configured to create the correct format.
