Couldn\’t rewrite query because Argument () of * was not able to be parsed as a string

[HugooB]

Hi there!

After days of debugging I just cannot figure out why my query is not working. This is the setup running Dgraph v21.12.0:

Scheme

type Chat {
  chat_id: Int! @id
  messages: [Message] @hasInverse(field: chat)
  title: String @search(by: [term, fulltext])
}

type Message {
  chat: Chat!
  message: String! @search(by: [term, fulltext])
  message_id: Int! @id
  timestamp: DateTime!
  user: User!
}

type User {
  messages: [Message] @hasInverse(field: user)
  user_id: Int! @id
  username: String
}

Query

query getChat($x: Int!) {
  getChat (chat_id: $x) {
    chat_id
    title
    messages { message }
  }
}

Variables

{"x": 1173233405}

Error

couldn’t rewrite query getChat because Argument (chat_id) of getChat was not able to be parsed as a string

Putting the chat_id directly into the query does work:

query getChatQuery {
  getChat(chat_id: 1173233405) {
    chat_id
    title
    messages { message }
  }
}

But separating the query and variables does not. Does anybody have any clue what I’m doing wrong?

After reading through the documentation I noticed that @id declarations can only be assigned to Strings types, as stated in the docs. However, the Dgraph v21.03.0 release notes state the following:

• Fix(GraphQL): adding support for @id with type other than strings (#7019)

So, it this a bug? @akon-dey encouraged me to file this Github issue, more info here:

I am having the same exact issue for this, did you managed to fix it ?

[MichelDiz]

There's no fix until we process the cherry pick of #7019

Perfect, thanks for the quick answer

[IDerr]

Is there any release planned for the cherry pick ? I just saw it was pushed 2y ago,
