  Review Method Definition: Check the method definition in the class or interface where the error is occurring. Ensure that the parameter types and scales match what is expected in the calling code.
  Update Calling Code: If the method signature has changed, update any code that calls this method to match the new parameter definitions.
  Check Inheritance: If the method is inherited, ensure that all derived classes are updated to reflect the changes in the base class or interface.
