Go tests doesn't play nicely on VS-code

[Art3miX]

Because we have 2 go projects, it can't pick both, so it just errors:
Error loading workspace: You are outside of a module and outside of $GOPATH/src. If you are using modules, please open your editor to a directory in your module. If you believe this warning is incorrect, please file an issue: https://github.com/golang/go/issues/new.

to "fix" it you need to open a single module in a new window, is there something to do with it?
