Serialization error when confirming email (custom signup flow)

Anvil Q&A
1

I’m using a translated version of the custom sign-up flow app. Everything is working fine except when I try to confirm an email I registered. Here is the error I get after clicking the confirmation link.

Error:

SerializationError: Cannot serialize arguments to function. Cannot serialize <class 'bytes'> object at msg['args'][0]

I thought it might be connected to Python 2 vs Python 3 bcrypt hashing referenced here: Custom Signup Flow Error on Sign Up

But I checked my custom signup app and it seems to have the correct code. Here is my signup app:

I can’t explain it, but it’s working now. I’m guessing I was changing too many things trying to troubleshoot and I should have slowed down.
