I think the issue is with OTP 28, not elixir 1.18.4. I've tested with elixir 1.18.3 and 1.18.2 both with OTP 28.0 and 28.0.1 and got the same error. Moving back to OTP27 it worked on the three versions.

@flmn we welcome PRs if you have a fix for OTP 28 🙏

Yeah it also helped me to go back to OTP 27, it's a bit unfortunate that the error exists on 28 but hopefully it can be fixed in the future :/

Don't know if related to this particular error, but we have many tests failing because this error on jose lib: potatosalad/erlang-jose#179

I comment some code, it can compiled!

`
defmodule MyAppWeb.Guardian.Pipeline do
use Guardian.Plug.Pipeline, otp_app: :my_app

#plug Guardian.Plug.VerifyHeader
plug Guardian.Plug.LoadResource, allow_blank: false
plug Guardian.Plug.EnsureAuthenticated
end
`

I thing the problem lies in Guardian.Plug.VerifyHeader.

I was not familiar with elixir macros, I studied it for a long time and couldn't even find what the problem was😂.

[Trolleger]

so what was the issue after all? (if you know)

Amazing! Are you planning to cut a new release so that we can benefit from the fix? Thanks!
