Can you please share a gopls log? Instructions on how to capture one here: https://github.com/golang/tools/blob/master/gopls/doc/troubleshooting.md#capturing-logs.

[Error - 11:20:37 PM] 2020/12/07 23:20:37 warning: diagnose go.mod: no metadata for bitbucket.org/<monorepo>/type [bitbucket.org/<monorepo>/type.test]

• VSCode is using root of the monorepo as workspace.

Thanks, @vishalkanaujia -- did bitbucket.org/<monorepo>/type or its test get deleted between the branches? There is a bug that will be fixed in v0.6.0 by https://golang.org/cl/275273. Can you please try building gopls with that patch to see if that fixes the issue? You can do so by following these steps.

$ git clone https://go.googlesource.com/tools
$ cd tools
$ git fetch https://go.googlesource.com/tools refs/changes/73/275273/1 && git cherry-pick FETCH_HEAD
$ cd gopls
$ go install

This didn't fix the issue for me, although it might just be my GOPRIVATE modules affected now.

@takeyourhatoff: If you don't mind, could you file a new issue following the steps here: https://github.com/golang/tools/blob/master/gopls/doc/troubleshooting.md#capturing-logs? It's usually easier to investigate different issues separately.

I still get the same errors.

Would you be able to share a complete log (starting from the initialize message)? I understand that might be difficult to anonymize, so if you'd prefer to share it privately, that could work too.

Alternatively, if you're able to reproduce this consistently, maybe you could describe the characteristics of your workspace and see if we can construct a public repro example.

I hit the problem again. I have sent you a mail with log details. The problem disappears after restarting VSCode.

Can you please make sure to add the following to your settings?

"go.languageServerFlags": [
	"-rpc.trace",
]

The logs you attached are missing some detail. Also, it looks like your workspace root is not a module, and it is outside of $GOPATH/src. I would recommend opening a module or a subdirectory of $GOPATH/src.

Thanks for the recommendations. I think the gopls behavior is correct if the monorepo is placed in the $GOPATH/src/ or just the module of the subdirectory is opened in the editor.

Yep, that is correct--gopls doesn't work well if you open your entire GOPATH. More details can be found here: #36899. Going to close this issue since it's been resolved.
