I seem to get two kinds of error messages in the VS Code developer tools,

The log just gets spammed continuously.

Expected behavior:

Type check, auto complete, etc. should consistently work

Actual behavior:

When I restart VS code, everything works fine.

Then, a while later (seconds/minutes; usually minutes), it just stops working and I get errors in the VS code developer tools console tab. If I restart VS code ("Reload window"), everything works fine again for a while, until those errors come back.

tsc works fine.

tsc -b -w works fine.

The project I'm working on is a composite project with 30+ sub-projects.

Not sure what other information I should provide.

It's kind of hard for me to reproduce the issue at will. I'm just writing a bunch of tests and every now and then, things just stop working.

Playground Link: None

No idea, maybe #30546 ?

But the logs seem very different.

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

@AnyhowStep Can you please turn on the tsserver log and when the issue reproduces share the complete log. That would make investigating this easier since from your description it happens only certain times, it feels like the action sequence might help what went wrong. If you want to share tsserver log more privately here are the steps.

With "typescript.tsserver.log": "verbose" enabled
Restart vscode or vscode insiders
Reproduce the problem
You can share the logs using
- either by sharing logs in the folder that gets opened by running open tsserver log from command palette
  or
- Run code --upload-logs on the command line (or code-insiders --upload-logs if using vscode insiders) and follow instructions and Then share the log file ID

AnyhowStep · 2019-06-25T19:53:49Z

I ran code --upload-logs and it told me to review the ~/.config/Code/logs/20190530T202503 directory.

However, when I run open tsserver log, it opens ~/.config/Code/logs/20190615T191737/exthost84/vscode.typescript-language-features/tsserver-log-Z1gGqW and contains tsserver.log, ti-28173.log

The timestamps seem different.

20190530T202503
20190615T191737

Do I just use code --upload-logs anyway? Is there a way to get code to upload the directory open tsserver log shows me?

AnyhowStep · 2019-06-27T21:14:16Z

Could you pass along some sample code which causes the crash? There are no repros in this issue - extra points if you can make it crash the playground too

gabrielsaints · 2019-12-09T16:09:53Z

I'm also seeing this, any fix?

tuanphamanh91 · 2019-12-12T03:06:53Z

@turbozv @cahtyw
Hi,
I just resolved this problem. this is my step:

remove Prettier - Code Formatter extension and re-install
Right-click and select Format document with...
Select TypeScript and Javascript Language Features
Select Prettier.
So the problem went away. I hope this can help
