AbsintheClient.attach/2 causes dialyzer errors with req 0.5.x

[fastjames]

Since I am the one who submitted the recent change allowing AbsintheClient's req dependency to go to 0.5.x, I need to follow that up with a problem I discovered while using the latest version of AbsintheClient.

I initially updated AbsintheClient without changing my version of req, so the problem wasn't immediately apparent. Today when I tried to update req, I ran into some unexpected dialyzer errors that I narrowed down to the function that calls AbsintheClient.attach(). The error is Function some_func/0 has no local return for the calling function.

In order to narrow the scope of investigation, I created a blank elixir application and added enough code to cause the same behavior I'm seeing in my application. You can view it at

Cloning the repo, then running mix deps.get && mix dialyzer should produce the dialyzer errors.

My hope is that I'm making a basic error in how I set up req and/or AbsintheClient.

Req provides a changelog entry for 0.5.0 (https://github.com/wojtekmach/req/blob/main/CHANGELOG.md#v050-2024-05-28) but I did not see anything in it that appeared to be relevant to the problem described above.
