Describe the bug

There is an issue with Conform and ESLint. The language server works correctly, validating errors, etc., but when I add it to Conform as a formatter, it doesn’t work and throws an error.

ESLint is installed both locally and globally.
I checked its presence in node_modules.
It was installed via LazyExtras.
Installed the latest, clean LazyVim package

What is the severity of this bug?

breaking (some functionality is broken)

Steps To Reproduce

1. Install a clean LazyVim package
2. Install a clean Angular project
3. Install all necessary dependency
4. Setup eslint as a formatter in conform config

Expected Behavior

You can use ESLint for formatting with Conform

Minimal example file

No response

Minimal init.lua

-- bootstrap lazy.nvim, LazyVim and your plugins
require("config.lazy")

Additional context

No response

eslint error: Unknown formatter. Formatter config missing or incomplete

This is supposed to happen when a formatter fails to initialize for some reason.

Setup eslint as a formatter in conform config

Can you share your whole eslint formatter setup please?

[alex-belost]

Completely clean installation of the LazyVim package with LazyExtras linting.eslint enabled.
I want to confirm that ESLint linting works correctly.

It looks to me like LazyVim is only configuring LSP formatting for eslint (which I've found to work better than the standalone CLI tool anyway). https://github.com/LazyVim/LazyVim/blob/main/lua/lazyvim/plugins/extras/linting/eslint.lua

conform does not have a formatter named eslint, only eslint_d. Something in your config is probably defining that, because I don't see it anywhere in LazyVim. In any case, from a conform perspective the answer is just "that formatter doesn't exist," anything else should be worked out in your config or with LazyVim.
