Extension seems to not start in VSCode remote container (devcontainer)

[altdsoy]

Hello, I am running my Elixir project within a container using VS Code remote container extension (devcontainer) with the ElixirLS extension. I wanted to try NextLS... However, I can't get it working. I checked in the troubleshooting section but was not able to find anything obvious.. The integrated terminal output I have for is not labeled Next LS but elixir-tools.vscode (not sure if this is relevant).. And I only have the following log: [info] files: undefined.. Also epmd is running.. I can't find anything in there ~/.cache/elixir-tools/nextls/bin/ which is the default value of the Installation Directory setting.. But it seems the extension is installed here ~/.vscode-server/extensions/elixir-tools.elixir-tools-0.15.1/bin I tried to change the Installation Directory setting to this but without success..

What do I do wrong? I'm running in Alpine Linux fwiw..
