Cowboy behaviour undefined

[Katur7]

Erlang LS gives me a warning that behaviour cowboy_rest is undefined. Even if I include "_build/default/lib" in include_dirs in erlang_ls.config.

If I also include "_build/default/lib/cowboy/src" in include_dirs in erlang_ls.config I get the warning: Issue in included file (18): behaviour cowboy_sub_protocol undefined

I made this small repo to reproduce the issue: Repo

Expected behavior I expected the cowboy_rest behaviour to be found by default.

Actual behavior The cowboy_rest behaviour is not found

Context

• erlang_ls version (tag/sha): 0.17.0
• Editor used: VS Code 1.57.1
• LSP client used: erlang-ls.erlang-ls v0.0.27

It's actually complaining about the cowboy_sub_protocol not being found in cowboy_rest. This is similar to this issue: https://github.com/erlang-ls/erlang_ls/issues/1024

I worked around this for now by adding:

code_path_extra_dirs:
  - "./_build/default/lib/*/ebin/"

to my erlang_ls.config.

Thank you @dweinstein. That works for me also :)

hi @plux was this issue fixed by some code change or is the workaround still best to use? I noticed you marked this ticket as completed so I was just curious if I should try updating my erlang_ls.config. Thanks for the work you're doing!

I think this issue still exists and we should investigate it further. I will open it again.

Unfortunately that workaround doesn't work for me with the behavior cowboy_middleware.

I think I have found the issue for this. I will submit a PR later.
