Solutions

1. Too many arguments were given for the function.
2. Reduce the argument count to at most the allowed maximum.

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.
