Errors when storing nil values

[alexcastano]

Hi,

Thank you for your incredible work :)

We are experiencing some crashes after storing some nil values using Cache.put_all([{:key, nil}], ttl: ttl). We use version 2.4.2.

The backtrace is:

Reading the code, it seems like we should not store nil values; however, I think this behaviour is not documented 😅

Thank you

Hey 👋 ! Yeah, you're right, by default in Nebulex v2 nil values are skipped and that is not documented. Thanks for reporting it, we need to add docs here. On the other hand (quick update), for Nebulex v3 which is ongoing, this is not a constraint anymore, any value will be allowed to be cached.
