logging library doesn't support Exceptions about firebase-functions-python HOT 1 OPEN

so i ran into this problem also. It seems that the logger is trying to serialize an exception which is not possible so you need to convert the exception to something that is serializable, like a string representation of the exception. Found this out thanks to this stackoverflow thread: https://stackoverflow.com/questions/68108446/typeerror-object-of-type-typeerror-is-not-json-serializable-python

This should resolve the problem:
logger.error("Unable to read quote from Firestore, sending default instead", error=str(e))

You also shouldn't be using a bare except so for a better message use something like:

except Exception as e:
    logger.error("Unable to read quote from Firestore, sending default instead", error=str(e))

from firebase-functions-python.
