  Solution:
  
  Check URI Template: Review the URI template definition in your SAP application. Ensure that it does not include unsupported characters like & in variable names.
  URL Encoding: If you need to include special characters in the URI, make sure to URL-encode them properly. For example, replace & with %26.
  Modify Input Values: If the error is caused by input values that include &, consider sanitizing or encoding these values before they are used in the URI.
  Review Documentation: Consult the SAP documentation for RESTful services to ensure that your URI templates conform to the expected format and character restrictions.
