Dialyzer issue

[mcesaro]

Hi there,
I'm not sure about the behavior of the erlang LS VS Code extension.

My configuration is the following:
Version: 1.80.1

Erlang LS VS Code ext version 0.0.40 Server (0.44.1 -> 0.48.0)
Published 11/17/2019, 22:56:41

Identifier erlang-ls.erlang-ls

In the output tab I see this warning message:

Warn  - 2:46:29 PM] [2023-07-24T14:46:29.804060+02:00] [warning] Cannot extract typer info., Class: error, Exception: undef, Stacktrace: [{dialyzer_plt,from_file,["/home/max/work/test/_build/default/rebar3_26.0_plt"],[]},{els_typer,collect_info,1,[{file,"/home/runner/work/vscode/vscode/erlang_ls/apps/els_lsp/src/els_typer.erl"},{line,302}]},{els_typer,get_info,1,[{file,"/home/runner/work/vscode/vscode/erlang_ls/apps/els_lsp/src/els_typer.erl"},{line,83}]},{els_code_lens_suggest_spec,init,1,[{file,"/home/runner/work/vscode/vscode/erlang_ls/apps/els_lsp/src/els_code_lens_suggest_spec.erl"},{line,29}]},{els_code_lens,lenses,2,[{file,"/home/runner/work/vscode/vscode/erlang_ls/apps/els_lsp/src/els_code_lens.erl"},{line,91}]},{els_code_lens_provider,'-run_lenses_job/1-lc$^0/1-0-',3,[{file,"/home/runner/work/vscode/vscode/erlang_ls/apps/els_lsp/src/els_code_lens_provider.erl"},{line,37}]},{els_code_lens_provider,'-run_lenses_job/1-lc$^0/1-0-',3,[{file,"/home/runner/work/vscode/vscode/erlang_ls/apps/els_lsp/src/els_code_lens_provider.erl"},{line,38}]},{els_code_lens_provider,'-run_lenses_job/1-fun-1-',2,[{file,"/home/runner/work/vscode/vscode/erlang_ls/apps/els_lsp/src/els_code_lens_provider.erl"},{line,38}]}] [els_code_lens_suggest_spec:init/1 L39] <0.486.0>

The application I'm working on is based on OTP 26

The thing I cannot explain is that in the error description:

[warning] Cannot extract typer info., Class: error, Exception: undef, Stacktrace: [{dialyzer_plt,from_file,["/home/max/work/test/_build/default/rebar3_26.0_plt"],[]}

the reference to the undocumented dialyzer_plt:from_file() function is suspect, since I can't find it in the dialyzer source code in the erlang OTP repository.
Maybe I'm wrong, but it looks like that without a PLT file, some features of the erlang LS are not available.
So the question is: Is this an els_typer bug or is there another way to achieve the dialyzer based features of erlang LS?

Thanks
