tree-sitter-elm.wasm not found

[jweir]

Starting vim with elm-language-server 2.7.1 I get the following error:

[coc.nvim] Request initialize failed with message: ENOENT: no such file or directory, open '../../../../../../opt/homebrew/lib/node_modules/@elm-tooling/
[coc.nvim] Server languageserver.elmLS failed to start: Error: Request initialize failed with message: ENOENT: no such file or directory, open '../../../
../../../opt/homebrew/lib/node_modules/@elm-tooling/elm-language-server/out/common/tree-sitter-elm.wasm'

Current Workaround

I adjusted the path to tree-sitter-elm to the below, but this probably isn't a great solution.

        const pathToWasm = (_b = initializationOptions.treeSitterElmWasmUri) !== null && _b !== void 0 ? _b : Path.relative(process.cwd(), Path.join(__dirname, '../../out/', "tree-sitter-elm.wasm"));

Your Environment

• Version used: 2.7.1
• Editor used: vim + coc
• Environment name and version (e.g. node.js 5.4): node v18.16.1
• Operating System and version: MacOS 13.4.1

Could be this change 1dd8d65#diff-1f963b5ae3613de37b5354a3da594cdef878e0715ad0eb3896bd701e2511b273R60

Same issue here with a relatively new version of NVIM. Using Packer and Mason and did a npm install -g @elm-tooling/elm-language-server though not sure that was needed.
Gonna try the workaround.
Where did you put this workaround @jweir?

[jweir]

@Chocrates I edited out/common/index.js line 74 under /opt/homebrew/lib/node_modules/@elm-tooling/elm-language-server/ – your location may vary.

Thanks that worked for me @jweir

Same error here. I paste the stack I got in neovim as it is slightly different from @jweir, in case it could helps

Just ran into same problem in Neovim using Mason for LSP business.

I've just downgrading the package rather than messing with the source

I think this issue is caused by a recent refactor of the code into separate folders. For example this section of code used to be in the src directory but was refactored into the src/common directory, which likely silently changed the computed directory for the tree-sitter-elm.wasm file:

elm-language-server/src/common/index.ts

Lines 60 to 65 in ddab044

	const pathToWasm =
	initializationOptions.treeSitterElmWasmUri ??
	Path.relative(
	process.cwd(),
	Path.join(__dirname, "tree-sitter-elm.wasm"),
	);

At the moment, I've shared a potential fix at #1070
Please let me know what you think 🙏

[jmbockhorst]

Fixed by #1070.

This needs a new server release to reach vim users
