  Solution:
  
  Separate Operations: Break down the operations into separate API calls. Instead of trying to create and update records in one call, make individual calls for each operation.
  Check API Documentation: Review the API documentation to understand the limitations and requirements for the operations you are trying to perform. Ensure that you are using the API as intended.
  Use Batch Processing (if supported): If the API supports batch processing, ensure that you are using it correctly. Some APIs allow multiple operations but require a specific format or structure.
