  Configuration Issues: There may be issues with the configuration of the data flow or mapping that leads to mismatches in the expected output.
  
  
  Transformation Logic: If there are transformations applied to the data, they may not be correctly implemented, leading to differences in the output.
  
  
  Solution:
  
  
  Review Data Structures: Check the schema definitions for both the request and response. Ensure that they are aligned and that all required fields are present in both datasets.
  
  
  Validate Data Types: Ensure that the data types for corresponding fields in the request and response match. If there are discrepancies, you may need to adjust the data types in your data flow or transformation logic.
  
  
  Check Mapping and Transformations: Review the mapping and transformation logic to ensure that it is correctly implemented. Look for any conditions or rules that may be causing the data to be transformed incorrectly.
  
  
  Debugging: Use debugging tools or logs to trace the data flow and identify where the mismatch occurs. This can help pinpoint the exact location in the data processing where the error is triggered.
  
  
  Testing: After making adjustments, perform tests with sample data to ensure that the request and response are now aligned and that the error no longer occurs.
