Solutions

1. Call setParameter(name, value) for every registered IN parameter before executing.
2. Verify the parameter name matches the registered name exactly.

When it happens

Trigger: A stored procedure / query parameter is bound or referenced inconsistently with its registration.

Common situations: Calling StoredProcedureQuery or Query with missing, misnamed, or mixed named/positional parameters.
