  Check Data Types: Verify the data type of the constant you are using. Ensure that it matches the expected result type of the rule or expression. You can do this by checking the definition of the constant and the expected output of the rule.
  Modify the Constant: If the constant is of the wrong type, you may need to create a new constant with the correct data type or modify the existing one to ensure compatibility.
  Review Rule Configuration: Go through the configuration of the rule or expression to ensure that all components are correctly defined and that there are no discrepancies in data types.
  Testing: After making changes, test the rule again to ensure that the error is resolved.
