Solutions

1. The argument's mapped type does not match the function parameter's declared type.
2. Cast the argument to the required type or pass a value of the correct mapped type.

When it happens

Trigger: A function call in a query supplies arguments that violate the function's signature.

Common situations: Passing the wrong number or types of arguments (e.g. untyped nulls, tuples) to HQL/SQL functions.
