What did you do?

Hello everyone, I started experimenting with mod. When I initialize the modules in my project, all libraries are loaded and github.com/satori/go.uuid is loaded accordingly.. But when starting go run server.go

What did you expect to see?

start without errors

What did you see instead?

I get an error {
"resource": "/d:/myProject/oauth/tokenstore/tokenstore.go",
"owner": "generated_diagnostic_collection_name#0",
"severity": 8,
"message": "cannot initialize 2 variables with 1 values",
"source": "LSP",
"startLineNumber": 41,
"startColumn": 20,
"endLineNumber": 41,
"endColumn": 30
}

I am using vscode.

My project is outside gopath

How can we recreate the problem?

This is an old and very well-known breakage. satori/go.uuid broke the public API here satori/go.uuid#66. When you shifted to modules, it took the latest stable release which had 1 variable.

A good tldr is here - satori/go.uuid#66 (comment)

So either lock to a newer version or wrap them with uuid.Must.

Folks have even forked it here - https://github.com/gofrs/uuid.

I am going to close the issue as this is not a bug in Go.

Thanks I got the same issue after migrating to modules for workaround a bug with grpc
