FunctionClauseError on `XPExpert.EngineApi.format/2`

[wingyplus]

I use expert on the neovim. Sometimes, this error show up when the editor request formatting.

[LSP][expert] RPC[Error] code_name = InternalError, message = "** (FunctionClauseError) no function clause matching in XPExpert.EngineApi.format/2\

This error disappear once restarting the LSP (with LspRestart) and show it again when using for a while.

FunctionClaudeError

love this typo 😆

This error disappear once restarting the LSP (with LspRestart) and show it again when using for a while.

I couldn't get it to go away with LspRestart. Not sure what all information I need to provide either.

[heywhy]

@wingyplus can you share how to reproduce the issue, though? I'm curious.

@wingyplus can you share how to reproduce the issue, though? I'm curious.

Sadly, I still cannot figure out the root cause. 😢

I am also seeing this happen locally. I'm not sure what causes it, but reopening the file (with :e in neovim) seems to fix it for a while.

Neovim 0.11.4, nightly of Expert

[heywhy]

My hypothesis here is that the Forge.Document.Store process restarted for whatever reason, making the server lose track of opened documents. I believe the only way to fix this is to identify what's making the process crash.

References

expert/apps/expert/lib/expert/provider/handlers/formatting.ex

Line 14 in 16c21e0

document = Forge.Document.Container.context_document(params, nil)

expert/apps/forge/lib/forge/document/container.ex

Lines 39 to 44 in 16c21e0

	def context_document(%{text_document: %{uri: uri}}, parent_context_document) do
	case Document.Store.fetch(uri) do
	{:ok, document} -> document
	_ -> parent_context_document
	end
	end

I'm seeing this with the most recent master:

Was there any other logs printed above that?

[andyleclair]

just this, which was from starting expert and opening a file:

The crash happened when I tried to go to definition on a function

[andyleclair]

So, after that, the LSP server was dead. Here's what I get for output after I restart the service. Seems like it's not properly handling the LspRestart command from neovim?

Ok, after trapping exits in the Store process, I can see that it doesn't appear to be dying, but I also don't see it in Process.list() which makes me think the name registration isn't working right? I think {:via, :global, {__MODULE__, entropy()}} might be wrong? Isn't it just {:global, _term}

Edit: No, that's wrong {:via, :global, ...} is fine.

If I open the console (via the script in /bin) I can access the data from the document, but when the running LSP tries to do it, it doesn't work.

@andyleclair you can join the unofficial discord and check the #editor-tools channel: https://discord.gg/qNaVqKXwxB all of the expert mantainers are in that server
We'd prefer to keep the github issues updated for transparency though
