Querying schema using gRpc client, returns empty object

I’m using the dgo client library.

Tried querying schema with gRpc connection with this code:

        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": [

        ]
      },
      {
        "predicate": "password",
        "type": "string"
      },
      {
        "predicate": "username",
        "type": "string",
        "index": true,
        "tokenizer": [
          "hash"
        ]
      }
    ]
  },

  }
}

Any issue with the gRpc client?

That does look like a bug. I see you also posted a GitHub issue for dgo. Let’s continue the discussion there.

Ah, the api.Response that’s returned in the query has .Schema field that should be checked instead of the .Json field.

Thanks for clarifying and it to the docs!
