  The SAP error message SADT_REST107: Invalid request, maybe LF is used instead of CRLF typically occurs when there is an issue with the formatting of the HTTP request being sent to the SAP system. This error suggests that the request is not properly formatted according to the expected standards, particularly in terms of line endings.
  
  Cause:
  
  Line Ending Issues: The error indicates that the request may be using LF (Line Feed) instead of CRLF (Carriage Return + Line Feed). HTTP/1.1 requires that lines in the request be terminated with CRLF.

  Solution:
  
  Check Line Endings: Ensure that the HTTP request is using CRLF (\r\n) for line endings
