  Invalid Assignment: The error usually arises when there is an attempt to assign a field symbol to a data object that is not compatible or does not exist.
  Scope Issues: The field symbol may be out of scope or not properly defined before the assignment.
  Data Type Mismatch: The data type of the field symbol does not match the data type of the target object.
