I believe the dialyzer errors are caused by elixir-lang/elixir#14837

[angelikatyborska]

This one as well: jeremyjh/dialyxir#563 but it was created before Elixir 1.19.0 was released 🤔 unless somebody tested on a rc version.

@jiegillet Did you encounter this error at work maybe? I have no idea what to do.

[neenjaw]

is it possible it is using an old plt that is incompatible with the new version?

[angelikatyborska]

The cache key on Github CI includes the exact Elixir version and file has of mix.lock, so unlikely. I also tested locally by deleting plts first, same results 😞

I've also encountered the dialyxer issue at work, unfortunately no amount of build and plt cleaning or config tweaking resolves the errors.

Hopefully it's fixed soon upstream

[angelikatyborska]

It worked! 🎉 It required upgrading dialyxir to 1.4.7 and Elixir to 1.19.2, as well as adding a flags: [:no_opaque] flag to the dialyzer config (as suggested in elixir-lang/elixir#14837 (comment))

This PR could be approved and merged right now, but I'm still waiting on an official 1.19.2 Docker image for the tooling repos.
