@decitrig Thanks for the report. I guess the extension fails to activate successfully.

Have you seen any popup or error messages when you opened the file and activated the extension?
Do you see any error or crash message in the extension logs output channel: View: Toggle Output > see Log (Extension Host) and Go output channels from the dropdown menu.

Change https://golang.org/cl/252826 mentions this issue: package.json: let some commands activate extension

I've just experienced this issue after VSCode updated my go extension has stopped working. I've checked my go env and everything seems to be working fine but for some reason now my extension fails

When I look in the log I see the following

[2020-09-15 13:00:34.159] [exthost] [error] Activating extension golang.go failed due to an error:

Okay so I downgraded back to v0.16.1 and it all seems to be working again for me

[hyangah]

That's strange - I am guessing when running with 0.16.2, the extension failed to find the go binary for some reason.
0.16.2 has only minor fixes around go test run compared to 0.16.1, otherwise they are identical.

@hyangah I'll try an upgrade again and see whether I get the same issue

[aranw]

@hyangah so I managed to upgrade the extension and it worked for a bit but after a restart I've ended up with the following error again

[2020-09-18 15:50:29.097] [exthost] [error] Activating extension golang.go failed due to an error:

Edit:

Adding the following to my settings.json seems to fix the issue

    "go.alternateTools": {
        "go": "/usr/local/bin/go"
    },
