I found out a problem on this, after running GO111MODULE=on go mod tidy && GO111MODULE=on go mod vendor, the go.mod gets the module github.com/nats-io/go-nats v0.0.0-00010101000000-000000000000 // indirect but this gives me an error on building:

➜ go build .
go: github.com/nats-io/nats.go@v1.8.1 used for two different module paths (github.com/nats-io/go-nats and github.com/nats-io/nats.go)

We don't want to add dependencies for tests at this time. I skip the tidy part. Also, not sure why this added the dependency on gnatsd/go-nats. We have updated code base to avoid that...
At any rate, I don't think we want to force Go 1.13 as a dependency at this point.

Thanks, I'll just update the modules and avoid tidy to push the PR. Sorry about the 1.13 line, my bad.

Passed, thanks for the heads-up on "tidy" @kozlovic. It was really messing things up.
