Well, I said I'm not an experienced python coder, and in this case I've
always seen 'self' as the unspecified argument, but it could be a key
argument. Would be nice to see all of the code and messages. And getting
a look at the build() function would tell it all.

If you're right that the error message says build() is expecting 2
positional arguments and 1 keyword argument, then simply dropping the
GOOGLE_APPLICATION_CREDENTIALS argument might just work.
