  Review Workflow Binding: Go to the workflow definition and check the binding settings. Make sure that the variables are correctly bound and that the data types are compatible.
  Debugging: If the issue persists, consider using debugging tools to trace the workflow execution and identify where the conversion error occurs. This can provide insights into the specific values being processed at the time of the error.
