Can you Ppease try collecting the TS Server log from the crashed instance:

1. Set "typescript.tsserver.log": "verbose"

2. Restart VS Code and reproduce the problem

3. Open the TypeScript section of the output panel

4. At the very top, find the first line that prints to path to the semantic error log file. It should look something like:

   [Info  - 19:54:59.247] <semantic> Log file: /Users/matb/Library/Application Support/Code - Insiders/logs/20200213T104930/exthost55/vscode.typescript-language-features/tsserver-log-ZT2zau/tsserver.log
   

   That file contains the typescript logs.

Look through that log file for the first error or stack trace you see. If you can share the log, I can also take a look to see if anything stands out

⚠️Warning: The TypeScript log may include information from your workspace, including file paths and source code. If you have any concerns about posting this publicly on Github, just let me know and we can arrange something else. On our side, we only use these logs to investigate issues like this

[rchiodo]

Unfortunately, I haven't reproduced the problem since. It happened just once.

[samschurter]

I'm able to reproduce it consistently now. I was working in a project and everything was fine, but with one particular file, IntelliSense shows one popup and then dies with the False expression error in the extension output. In the logs it looks like the typescript server is working and doing all the setup, but as soon as I type one character, it crashes.

The logs continue for several thousand lines after this that look pretty much identical

Please share the complete tsserver log along with the steps to repro. Thanks

[samschurter]

tsserver.log

Repro steps

1. Open a Vue 2.7 project in VS Code (it's not public so I can't share the repo)
2. Open frontend/src/store.js (You can see the project structure and loaded files in the log, as well as the full text of store.js)
3. Hover over anything. Intellisense (and the language server) function properly
4. Make any change to the file
5. Hover over any item. Intellisense is down and the language server has exited with SIGTERM.

Other files in the project will eventually crash the server, but store.js is very reliable and crashes the language server after exactly one character entered, anywhere in the document.

Even though the stack trace does not point to any extension files besides the built-in TypeScript language features, I tried turning off all extensions and the crash went away. I turned them back on one at a time and narrowed it down to TypeScript Vue Plugin (Volar) from this repo.

Since the stack trace doesn't list any files from that extension, I'm not sure if this is on them, or the TypeScript language features

[sheetalkamat]

I think this is fixed by #56356
Can you try nightly typescript version and see if this is fixed

[samschurter]

I haven't tested thoroughly, but it seems like that did fix it! Thanks
