Same here...

[waderyan]

@kai23 thank you for opening this issue. I have observed similar behavior and think it could be related to Microsofty/TypeScript #10735 .

I cannot reproduce right now

Can you help me track this down?

Add this to your settings

"typescript.tsserver.trace": "verbose"

Additionally, set the environment variable TSS_LOG=-level verbose. there should be a log file written next to tsserver.js that would have the form of .log[0-9]+

and :

[Trace - 9:12:34 PM] Response received: projectInfo (4). Request took 2 ms. Success: false . Message: Error processing request. Cannot read property 'projectFilename' of undefined

Edit: Because I needed to work today, I installed the project manager extension. I removed it, but still.
Edit 2: have seen this issue ( #8212 ) but don't understand how it was fixed
Edit 3: adding a jsconfig.json file juste makes things worst, no autocomplete at all ( with this :

{
    "compilerOptions": {
        "target": "ES6"
    },
    "exclude": [
        "node_modules"
    ]
}

Edit 4 : same things happen in the insiders build

PS : didn't found the log file. Maybe I'm not searching the right place ?

@kai23 thanks for logging this for us. Sending to TS team to look into further.

Failed to repro the issue on windows and OS X. @kai23 I noticed you are using a non-English copy of VSCode. Does your "XXX" folder have a non-English folder name? Just a thought.

[kai23]

Hey,

My XXX folder have this form = mbp-kai without any special chars

Could not get to repro it locally on latest either. closing for now. please reopen if the issue is still there.
