Describe the bug

It is somewhat difficult to specifically point out exactly what the problem is, but this issue seems to have started with the latest VSCode update (I also updated go from 1.20.5 to 1.20.6 during the same timeframe), but in short, I'm getting many broken import problems that were not happening before, and the broken imports seem to cascade into other errors.

For example, if I clone the github repo: https://github.com/opencost/opencost and then open VSCode in the newly cloned directory, I immediately get the following as one of the many broken import errors:

could not import github.com/opencost/opencost/pkg/kubecost (import failed for "github.com/opencost/opencost/pkg/kubecost": internal error while importing "github.com/opencost/opencost/pkg/kubecost" (runtime error: index out of range [3142] with length 28); please report an issue)

The runtime error: index out of range [3142] with length 28 is an error I continue to see in in the problems tab for a few other imports.

I've tried:

• go clean -cache
• go clean -modcache
• reinstalling the go tools

A clear and concise description of what you expected to happen.

Steps to reproduce the behavior:

1. Clone repo https://github.com/opencost/opencost
2. Open Repo in VS Code
3. Note Broken Imports Errors with runtime error: index out of range [X] with length Y

Note: After rolling back to gopls v0.12.4, I no longer see the broken imports errors. I did this by running:

go install golang.org/x/tools/[email protected]

and then in VS Code, Ctrl/Cmd+Shift + P -> "Go: Restart Language Server"

Thanks for the report. This is golang/go#61670, which is fixed in v0.13.1-pre.1. We'll release v0.13.1 later today.

In the meantime:

go install golang.org/x/tools/[email protected]

Sorry for the breakage.

@findleyr Thank you for the info, that definitely fixes my issues. Much appreciated!

[findleyr]

This should now be fixed with the v0.13.1 release.
