Receiving error "Vue Semantic Server client: couldn't create connection to server." since upgrading to 1.0.0 #1942

alan-strickland-red · 2022-10-07T15:20:58Z

Hi,

Since VSC upgraded to Volar to 1.0.0 automatically this afternoon I am getting errors when loading .vue files.

The output window for the Vue Semantic Server shows the following errors repeatedly:

[Error - 16:15:48] Server initialization failed.
  Message: Request initialize failed with message: Cannot read properties of undefined (reading 'createLanguageService')
  Code: -32603 
[Error - 16:15:48] Vue Semantic Server client: couldn't create connection to server.
  Message: Request initialize failed with message: Cannot read properties of undefined (reading 'createLanguageService')
  Code: -32603 
[Info  - 16:15:50] Connection to server got closed. Server will restart.

The output window for the Vue Syntactic Server shows the following errors repeatedly:

[Error - 16:15:48] Server initialization failed.
  Message: Request initialize failed with message: Cannot read properties of undefined (reading 'createLanguageService')
  Code: -32603 
[Error - 16:15:48] Vue Syntactic Server client: couldn't create connection to server.
  Message: Request initialize failed with message: Cannot read properties of undefined (reading 'createLanguageService')
  Code: -32603 
[Info  - 16:15:50] Connection to server got closed. Server will restart.

I have downgraded to Volar 0.4 and that has resolved the issue for the time being.

The text was updated successfully, but these errors were encountered:

It seems a same problem: #1880 (comment)

But I don't know how it resolve, can you try reinstall extension and restart vscode?

I've just tried 1.0.0-rc.5 in ST and got it:

I suppose it has to do with initializationOptions but if this payload alone doesn't help you then I can investigate further.

(note that it tries to use typescript v4.8.4)

EDIT: Also tried with @volar/vue-language-server@1.0.0 but the same

alan-strickland-red · 2022-10-07T15:49:01Z

I have tried re-installing it and restarting vscode and even restarting the machine.

My colleague and I have the same setup and his is working with the latest extendion so I enabled the verbose logging you mentioned on the other thread and compared it between the two environments, the only difference is in the typescript initializationOptions where the tsdk path on mine is pointing at the workspace and his is posing at the global install.

Working

@rchl please try update initializationOptions (See #1916):

That helped. Thanks.

rchl · 2022-10-07T15:59:45Z

Failing

In my case above it was about the path pointing to a file rather than the lib dir. You've masked yours in the failing case so hard to tell whether it's the same issue.

Also I guess make sure that the directory and files within it do exist.

johnsoncodehk · 2022-10-07T16:00:00Z

@alan-strickland-red I just found a way to reproduce it under specific conditions, please wait for v1.0.1.

Reproduce steps:

Change to Use VSCode Version tsdk in status bar
Clear .vscode/settings.json content.
Change to Use Workspace Version tsdk in status bar

alan-strickland-red · 2022-10-07T16:02:40Z

@johnsoncodehk Thank you.
@rchl If it helps the masked path was pointing at the root directory of the VSC workspace

johnsoncodehk · 2022-10-07T16:04:16Z

@alan-strickland-red You can try to change to VSCode Version tsdk in status bar to avoid this problem for now.

@johnsoncodehk That's fixed it. I changed to "Use Workspace Version 4.8.4", note of interest switching back to "Use VC Code's Version" also works.

I installed the previous version of fly and it worked for me. as a temporary solution.

Sorry to bother you all, but this problem has prevented me from using vscode to write vue projects, and using the above method has not solved the error and plugin failure.

Same problem, I think this must have happened with an update as it only started yesterday. When I check the output I see:

Request initialize failed with message: Can't find typescript.js or tsserverlibrary.js in ms-vscode.vscode-typescript-next

So what this tells me is that this problem has something to do with the Microsoft official typescript extension. What to do?, Here's some solution that'll work. Open your extension list and disable this extension for your workspace.

Alternatively, install a different version of the extension.

However, for me, it only worked after disabling the extension. I guess there might be some incompatibility with Volar and vscode-typescript-next recent changes.

Please update your extension to v1.4.3 or later, and please don't reply on an obsolete issue.

MartinsOnuoha · 2023-04-23T03:35:23Z

Please update your extension to v1.4.3 or later, and please don't reply on an obsolete issue.

@johnsoncodehk Thanks, I see this is resolved in v1.4.3.
I wouldn't call it "replying to an obsolete issue" since this was happening as of v1.4.2 and x.x.3 was only published 11 hours ago 🙂. Thanks

GaoJuqian · 2023-04-23T03:39:34Z

👍

johnsoncodehk · 2023-04-23T03:40:42Z

I mean this issue (#1942) is obsolete, it has nothing to do with the problem with the new version. You should be able to see the prompt message from github.

MartinsOnuoha · 2023-04-23T03:46:29Z

I agree, unfortunately, it happened to be the only related issue with the most engagement and most recent comment. Thanks again.
