  Check Object Types: Verify the definitions of the source and target object types. Ensure that they are compatible in terms of data types and structures.
  Adjust Workflow Bindings: If the binding is incorrect, adjust the workflow bindings to ensure that the source and target types match. This may involve changing the data type or modifying the workflow configuration.
  Use Compatible Types: If necessary, use a compatible type or convert the data type in the workflow to ensure compatibility.
  Review Workflow Configuration: Go through the workflow configuration to ensure that all bindings are set up correctly and that there are no discrepancies.
  Test Changes: After making adjustments, test the workflow to ensure that the error is resolved and that the workflow functions as expected.
