What you wanted to do

I download the latest version dgo ,and I want to use the demo.but when I login the gRpc port 9080
It’s failed.

=== RUN   Example_getSchema
2021/02/22 16:30:38 While trying to login rpc error: code = Unknown desc = invalid username or password

this is the code

conn, err := grpc.Dial("", grpc.WithInsecure())
	if err != nil {
		log.Fatal("While trying to dial gRPC")

	dc := api.NewDgraphClient(conn)
	dg := dgo.NewDgraphClient(dc)
	ctx := context.Background()

	// Perform login call. If the Dgraph cluster does not have ACL and
	// enterprise features enabled, this call should be skipped.
	for {
		// Keep retrying until we succeed or receive a non-retriable error.
		err = dg.Login(ctx, "groot", "password")
		if err == nil || !strings.Contains(err.Error(), "Please retry") {
	if err != nil {
		log.Fatalf("While trying to login %v", err.Error())

and when I debug I found the context is empty .I don’t know if context is empty would influence the dgo client login?
I 'm sure 9080 port is alive .
I run dgraph by
`` docker run --rm -it -p 8080:8080 -p 9080:9080 -p 8000:8000 -v ~/dgraph:/dgraph dgraph/standalone:v20.11.1`
