Settings don't seem to be applied when using linter from CLI

How are you using the lua-language-server?

Expected Behaviour

I am using the language-server.exe binary from the release archive for linting in a pipeline.
As I want to use the same linting settings as in the dev environment, I use the --configpath flag for passing the path of the settings file.
e.g. .\language-server\bin\lua-language-server.exe --configpath .\.vscode\settings.json --check .\Coding\Demo\workshop_01

I expect the language-server.exe to apply these settings and e.g. not report for a diagnostic I turned off in the settings file.

Actual Behaviour

In all of my attempts (using settings.json from .vscode, setting up a .luarc.json with the same settings) I couldn't get the tool to use the settings file.
So no settings were applied, and also the log files were saying that no settings were loaded:

[17:59:24.472][warn] [#0:script\config\loader.lua:116]: No config?	nil
[17:59:24.472][warn] [#0:script\config\loader.lua:116]: No config?	nil
[17:59:24.472][info] [#0:script\provider\provider.lua:61]: Load config from client	fallback
[17:59:24.472][info] [#0:script\provider\provider.lua:62]: nil

Reproduction steps

1. Prepare lua-language-server.exe
2. Prepare lua source that will result in a diagnostic problem
3. Prepare settings file that will disable the diagnostic that would find a problem from step 2
4. Execute the binary supplying (2) with the --check flag and (3) with the --configpath flag

Additional Notes

I tried following the Wiki pages to find out why the settings I try to use are not applied, but I am not sure if I use the flag wrong (wrong flag, wrong syntax, wrong settings format?) or if the language-server itself just does not use it due to some bug.
I also use the --logpath flag similarly and don't have any problems with that.

Log File

No response

Should be --configpath=.\.vscode\settings.json

I cannot reproduce it

Can you find Load config from specified in log?

[AndreaWalchshoferSCCH]

No, my logs only say "Load config from client fallback"

I created a smaller repository showcasing my issue here: https://github.com/AndreaWalchshoferSCCH/lls-cli-issue-sample - maybe you can reproduce it this way?

[AndreaWalchshoferSCCH]

We've done some additional experiments/rework of our scripts now, and have found a way where it looks like its working correctly.
For us, the solution is to use absolute paths (starting $PSScriptRoot in our case).
I don't know if there's a way to help users find the issue why their configuration isn't loaded? But maybe even just this issue with the comments helps someone in the future.

I have the same issue. The absolute path @AndreaWalchshoferSCCH worked:

.luarc.json file does not get found.

lua-language-server --check ./lua --checklevel=Warning --logpath . --configpath .luarc.json
Diagnosis complete, 65 problems found, see ./check.json

But this works

lua-language-server --check ./lua --checklevel=Warning --logpath . --configpath /Users/nikolausbrunner/Documents/dev/repos/terra-theme/terra.nvim/.luarc.json
Diagnosis completed, no problems found

Both commands were run on the root directory from the project.
