ts_ls fails to install

[arzt-arsch]

My lazy-lsp looks like this:

      require('lazy-lsp').setup {
        preferred_servers = {
          python = { 'pyright', 'ruff_lsp' },
          c = { 'clangd' },
          javascript = { 'eslint', 'stylelint_lsp', 'ts_ls' },
          typescript = { 'eslint', 'stylelint_lsp', 'ts_ls' },
        },
        excluded_servers = {
          'efm',
          'diagnosticls',
        },
      }

But when I enter any typescript buffer I get this message: Client ts_ls quit with exit code 1 and signal 0.

:LspLog looks like this:

Any help is appreciated. Thanks!

It is possible you are on older nixpkgs. I recommend to use the unstable channel.

You can check if you are on unstable with nix-channel --list and if so then you can try to update to latest with nix-channel --update.

Switching to unstable resolved the issue. Thank you very much for this plugin!
