Type in QueryWithVars

Users

Given I have a node:

<_:1> <type:emailAccount> "" .
<_:1> <name> "test@example.com" .

I want to be able to retrieve the uid given the name and has(<type:emailAccount>).

I am trying to build the query using QueryWithVars and the golang api.

The query works with a hardcoded $type variable.

    variables := map[string]string{
		"$name": Name,
		// "$type": Type,
	}

	q := `
	query uid($name: string)
	{
		uid(func:eq(name, $name)) @filter(has(<type:emailAccount>)) {
		  uid
		}
	  }
	`
	resp, err := txn.QueryWithVars(ctx, q, variables)
	if err != nil {
		return "", err
	}

If i try to use $type as variable, returns the error: rpc error: code = Unknown desc = Got empty attr for function: [has].

What should be the query in order to work using $type to call has($type)?

Thanks

GraphQL variables are not supported in predicate names right now. Feel free to file an issue and we can support it.
