TypeError exceptions in stripe processor

we're still getting a bunch of exceptions in prod, here's one example:

we should figure out what we do with those exceptions. right now we have alerts when exceptions come up, and it seems worthwhile to fix those, but if we're not going to fix them, i'm probably just going to remove those alerts.

for now i'll make a silence to hide them from our dashboards at least, because this is a bit noisy.
