Live-share: Missing Intellisense/Trigger Suggestion in LiveShare Session

[WonderPanda]

In a new LiveShare session, none of the participants are able to see intellisense or trigger suggestion for code blocks. The host is able to trigger suggestions just fine (although participants can't see them when following host).

We tested in both TypeScript and C# code bases. Type checking seems to work fine. If a participant misspells an attribute or method for example, it will be properly underlined as an error with hover capabilities but again, no intellisense/autocomplete at all.

What was your system configuration?
Product and Version [VS/VSCode]: VsCode 1.42.1
OS Version[macOS/Windows]: Linux and Mac
Live Share Extension Version: 1.0.1653
Target Platform or Language [e.g. Node.js]: C# and Typescript (React)

Steps to Reproduce / Scenario:

1. Start new LiveShare session using shareable link and Invite participant
2. Observe that participant is unable to trigger intellisense or suggestions

Please attach logs to this issue:
You can access them via the Live Share: Export Logs command from the command palette (ctrl + shift + p) and attach them to this issue

Hello @WonderPanda, thanks for reaching out.
are the host and the guest using VSCode right?

[WonderPanda]

Yes both host and guest are using VsCode

[micheleberetta98]

Is there any news about this? I'm having the same problem (VSCode 1.43 on macOS).

[daytonellwanger]

Yes, we should be releasing a fix early next week!

Note: it's by design that if the host triggers completion it's not visible to the guest. However, if the guest triggers completion, they should get the same results that the host would.

@daytonellwanger has that new version been released? I am up to date with all the latest extensions but am still experiencing this issue with my team.

Product and Version [VS/VSCode]: VsCode 1.43
OS Version[macOS/Windows]: Mac
Live Share Extension Version: 1.0.1847
Target Platform or Language [e.g. Node.js]: Typescript (React)

[daytonellwanger]

@jleider , yes the fix should be in 1.0.1847. I wonder if you're hitting a separate issue than the one I fixed.. Same repro? Guest triggers completion and doesn't see anything?

[jleider]

@daytonellwanger Yes, usually intellisense (hover/completion) works as expected but sometimes it just doesn't work from the beginning or if it is working initially it will stop working at some point during the shared session.

[jleider]

The later ones are host logs, the earlier ones are guest logs. IntelliSense was mostly working during host sessions but was not working for the initial guest session.

I'll have my coworker upload his logs as well.

[daytonellwanger]

Ok, thanks! In that case, if it's not happening 100% of the time from the very beginning of the session, this is a separate issue than the one I solved. I'll see if I can find anything in your logs that indicates the issue..

Any suggestions on how I could try to repro? How often do you find language services stop working? Does it happen when multiple people are typing simultaneously? On poor network connections? On large projects? (All just example questions btw.)

[johndatserakis]

Thank you @daytonellwanger, here are my logs as well.

@daytonellwanger We have a fairly large project but that doesn't seem to be the issue as sometimes it works flawlessly. Then again, when its not working with one host it seems to not work regardless of how many times you reconnect. When its working at first it can start failing after 5-10 minutes or so. Unfortunately, I haven't noticed a pattern of when it happens or not.

[daytonellwanger]

Thanks! That's already very useful info.
