This looks correct!

Are you sure, the error is in the above line? I doubt it very much.
There is not "map" around in the code, you show us.

Python and Zope also provide tracebacks. These are *very* valuable
information to localize errors. Whenever you report a problem
involving an exception, you should provide both "Error Type"
and "Error Value" (as you do above) and also at least
the last lines of the traceback (if it is not too long, the complete one).
It tells you (and us) where precisely the error was detected.
