New Authelia version deprecates and changes several fields

[sivertism]

My Authelia broke after updating, and had the following error and warnings in the syslog.

There is one error: error decoding 'identity_providers.oidc.issuer_private_key': could not decode to a *rsa.PrivateKey: asn1: syntax error: data truncated Guess this is a consequence of the update, as I haven't changed the key. Have you experienced similar issues?

Then there are some deprecation warnings. It says no action required, but would be good to update regardless. Filing this here as it'd be pretty easy to miss these since they're just printed in a syslog.

I didn’t experience that issue with the private key. It’s weird that the error says data truncated. I’ve see that kind of error when the file was empty.

Thanks for posting those deprecation messages. I’ll get to those.

Turns out I must've deleted one line of text in the middle of the key in my secrets yaml... guess this is why we review changes before pushing!

Works again now. Guess there's no rush to fix this as Authelia v5.0 seems pretty far away.
