Version:

### What version of Dgraph are you using?

v21.03.0

### Have you tried reproducing the issue with the latest release?

Yeah.

### What is the hardware spec (RAM, OS)?

n/a

### Steps to reproduce the issue (command/config used to run Dgraph).

Run:

```auto
const txn = dgraphClient.newTxn();
const req = new dgraph.Request();
req.setQuery('schema {}');
const result = await txn.doRequest(req);

```

### Expected behaviour and actual result.

I expected to get the full schema, all types and predicates.

I get this error:

```auto
TypeError: Cannot read property 'toObject' of undefined

```

`req.setQuery('schema(type: Foo) {}')` works, successfully returning all the fields in type Foo.
