  Cause:
  
  Unsupported JSON Type: The specific JSON type being processed may not be supported by the XSLT writer. This can happen if the JSON structure is complex or if it includes data types that the XSLT transformation does not know how to handle.

  Check JSON Structure: Review the JSON data being processed to ensure that it conforms to the expected structure and types that the XSLT writer can handle. Simplifying the JSON structure may help.
  Update XSLT: If you have control over the XSLT, consider updating it to handle the specific JSON types or structures that are causing the issue. This may involve adding additional templates or logic to manage unsupported types.
  Use Alternative Transformation: If the XSLT writer cannot handle the JSON type, consider using an alternative method for transforming the data, such as using a different transformation tool or library that supports the required JSON types.
  Check SAP Notes: Look for any relevant SAP Notes or updates that may address this issue. SAP frequently releases patches and updates that may resolve compatibility issues.
