"Client 1 quit with exit code 2 and signal 0" with twig filetype

[dklymenk]

I want to use prettier with twig via efm. I have prettier and the necessary extension for twig installed globally. Prettier works fine via both cli and efm. Here are some relevant lua configs:

local prettier_twig = {formatCommand = "prettier --tab-width 4 --stdin-filepath ${INPUT}", formatStdin = true}

require"lspconfig".efm.setup {
    cmd = {DATA_PATH .. "/lspinstall/efm/efm-langserver"},
    init_options = {documentFormatting = true, codeAction = false},
    filetypes = {"lua", "python", "javascriptreact", "javascript", "typescript","typescriptreact","sh", "html", "css", "json", "yaml", "markdown", "vue", "twig"},
    root_dir = require('lspconfig/util').root_pattern("node_modules", "tsconfig.json", "jsconfig.json", ".git"),
    settings = {
        languages = {
            ...
            twig = {prettier_twig}
        }
    }
}

So formatting works, but every time I exit vim I see "Client 1 quit with exit code 2 and signal 0" error. Relevant logs from ~/.cache/nvim/lsp.log:

One of the errors is 2021/05/11 14:36:31 lint for LanguageID not supported: twig\n, but I'm not exactly sure if disabling linting would resolve other errors.

Actually, while formatting works flawlessly, it also produces a bunch of "error" logs in ~/.cache/nvim/lsp.log. Stuff like no configuration file and invalid memory address or nil pointer deference is present there as well, but I honestly don't care about how clean those logs are, I kinda only care about the Client 1 quit with exit code 2 and signal 0 error when I close vim.

Please let me know if I should to provide any additional information. Thanks.

I am seeing a similar issue with efm on both python and lua file types. Funnily enough it only seems to happen when quitting neovim without writing (i.e :q gives the error while :wq does not).

Everything seems to be working fine though.

Same here. Is there any setting that controls this? While this is solved, how could I "suppress" this message?

[mattn]

As far as I understand, this should be fixed.

[mjlbach]

For everyone asking about this, it's neovim that prints the warning, not EFM.

@mattn @mjlbach I started getting this yesterday on 0.0.31 which unless I'm mistaken includes the commit above. Are you not seeing it anymore?
