TypeError: Cannot read property 'symbol' of undefined in 'unknown' during 'completionInfo' #35036

This issue comes from crash dumps in telemetry. We've tried to de-duplicate issues on a best-effort basis, comparing the sequence of methods called and the command requested while ignoring line numbers.

I've been noticing this issue for the past few months (Windows), and have tried everything short of a reformat-- reinstalling, running in WSL, running my own Typescript version. Let me know if I can provide any information to help fix this.

herberthobregon · 2019-11-26T20:03:04Z

In my particular case it is a problem of firebase web. And its empty import...
in empty-import.d.ts

export = undefined

in this point, autocomplete of tsserver crash.

the solutions is to move the firebase into the some-package and install this package with yarn add file:./some-package

Markonis · 2019-12-02T19:30:03Z

I've just spent an hour trying to find a solution to this. Thanks @herberthobregon, indeed it was the Firebase SDK. For me the solution was even simpler. I just deleted the file empty-import.d.ts in node modules under the firebase package. Works fine for now...

herberthobregon · 2019-12-02T22:01:55Z

@Markonis The problem is when you install another dependency on your project, empty-import.d.ts will be added again. Eliminating it, I realized that this was the mistake, but to give you a permanent solution in what typescript links the solution to its main branch, you must do the above

Markonis · 2019-12-02T22:03:44Z

@herberthobregon Makes total sense, thanks! 👌 What about just commenting that line in the file?

danielkcz · 2019-12-04T18:43:41Z

I was experiencing "low performance" of autocomplete in vscode for a few weeks now, but it was only with a specific project. Today I realized it might be tsserver related, I turned on logs for the first time ever and this error popped up there. Now I know why, yes, Firebase is the culprit. Thanks a lot for finding this, saves a lot of nerves :)

~~I wonder, has anyone reported it back to Firebase? Or what are the next steps here? Is it something that will be fixed on the TS side?~~

Nevermind, it seems to be already fixed, just not released yet firebase/firebase-js-sdk#2379.

herberthobregon · 2019-12-05T15:17:28Z

@Markonis it is exactly the same, when you reinstall another dependency it will rewrite the file. as I said before, you should wrap firebase in a local package so that it does not index typescript server.

this is the temp solution 😪

yamachu · 2019-12-07T16:52:01Z

This issue maybe has solved by #35504
Could you try to use nightly typescript https://marketplace.visualstudio.com/items?itemName=ms-vscode.vscode-typescript-next and set VSCode version 3.8.0-dev.20191206

ref: #35458
fixed?: #35232 #35370

jassmith · 2020-01-06T00:21:01Z

@yamachu just FYI the nightly does indeed solve the issue with firebase SDK.

danvk · 2020-01-08T21:57:29Z

Two things that would be helpful here:

vscode could surface this crash more explicitly. The way I experienced it was that I suddenly got lots of "No suggestions" for autocomplete in situations where there clearly were valid completions. I assumed it was some kind of language service timeout due to complicated types until I dug into the tsserver logs.
An easier way to disable bundled typings with bugs in them. I've tried adding node_modules/firebase/empty-import.d.ts to the exclude section in tsconfig.json as well as compilerOptions.paths but to no avail. For another example of where this would have been helpful, see Type RequestTransformFunction should be RequestTransformFunction alex3165/react-mapbox-gl#666

I have the same error in vscode when triggering intellisense at the end (EOL) of a word, the intellisense is not working anymore after the exception is throwed up
