Get query result of upsert block

[wildan2711]

Hi,

Is it possible to retrieve the query result of an upsert block? I checked the resp.Json field of the api.Response from tx.Do, it returns an empty object {}.

Here is an example code.

schema := `username: string @index(term) @upsert .
email: string @index(term) @upsert .
no: int @index(int) @upsert .
name: string @index(term) .

type User {
	name
	username
	email
	no
}`

err := c.Alter(context.Background(), &api.Operation{Schema: schema})
if err != nil {
	log.Println(err)
}

query := `{
	q2 as var(func: type(User)) @filter(eq(username, "wildan")) { uid }
	q3 as var(func: type(User)) @filter(eq(email, "wildan2711@gmail.com")) { uid }
}`
condition := `@if(eq(len(q2), 0) AND eq(len(q3), 0))`
jsonData := `{"dgraph.type":"User","name":"H3h3","username":"wildan","email":"wildan2711@gmail.com","no":1}`

tx := c.NewTxn()

assigned, err := tx.Do(context.Background(), &api.Request{
	Query: query,
	Mutations: []*api.Mutation{
		&api.Mutation{
			Cond:    conditionString,
			SetJson: jsonData,
		}
	},
	CommitNow: true,
})

log.Println(string(assigned.Json), assigned.Uids)

tx = c.NewTxn()

assigned, err = tx.Do(context.Background(), &api.Request{
	Query: query,
	Mutations: []*api.Mutation{
		&api.Mutation{
			Cond:    conditionString,
			SetJson: jsonData,
		}
	},
	CommitNow: true,
})

log.Println(string(assigned.Json), assigned.Uids)

Which returns:

2020/01/04 13:16:01 {} map[dg.675717852.13:0x4e27]
2020/01/04 13:16:01 {} map[]

Thanks.
