ORA-06512: At line (error stack location)
What it means
Not an error by itself: it is a stack line telling where the error above it happened ("at owner.unit, line N"). The real error is the first ORA- code in the stack.
How to fix it
Read the first error in the stack, then go to the unit and line named by ORA-06512. In handlers log DBMS_UTILITY.FORMAT_ERROR_BACKTRACE to keep this information when re-raising.
