It's possible that the way your environment is configured, you're only
seeing the last error message. Just speculating, but it's possible that the
first message said the code of the function was invalid because of the
context reference, and the second message said that the function didn't
exist (which would be a spurious error caused by the function being
invalid.) How are you running the transformation, and (if you can reproduce
it) what exactly did the error output look like?
