Querying schema using gRpc client, returns empty object

[wildan2711]

Tried querying schema with gRpc connection with this code:

        d, err := grpc.Dial("localhost:9080", grpc.WithInsecure())
	if err != nil {
		panic(err)
	}

	c := dgo.NewDgraphClient(
		api.NewDgraphClient(d),
	)
        schemaQuery := `
		schema {
			type
			index
			reverse
			tokenizer
			list
			count
			upsert
			lang
		}
	`

	tx := c.NewTxn()
	resp, err := tx.Query(context.Background(), schemaQuery)
	if err != nil {
		return nil, err
	}

	var queryResult struct {
		Data []Schema
	}
	log.Println((string(resp.Json))

All it logs is just an empty object {}.

Tried querying using HTTP, seems to return schema as normal.

~$ curl -X POST localhost:8080/query -d $'
schema {
type
index
reverse
tokenizer
list
count
upsert
lang
}' | jq

      },

        "tokenizer": [

    ]

Any issue with the gRpc client?

Tried with HTTP client in Go, works fine too.

        schemaQuery := `
	schema {
		type
		index
		reverse
		tokenizer
		list
		count
		upsert
		lang
	}
`
	r := bytes.NewReader([]byte(schemaQuery))

	resp, err := http.Post("http://localhost:8080/query", "application/json", r)
	if err != nil {
		t.Error(err)
	}
	defer resp.Body.Close()

	data, _ := ioutil.ReadAll(resp.Body)
	log.Println(string(data))

Instead of resp.Json, the schema is returned at resp.Schema.

Thank you for the clarification. Is this in the docs somewhere?

[danielmai]

It's now in the README's query docs: https://github.com/dgraph-io/dgo#run-a-query

Cool, thanks!
