Report a Dgraph Client Bug

What Dgraph client (and version) are you using?

  • Dgo
  • PyDgraph
  • Dgraph4J
  • Dgraph-js (v21.03.1)
  • Dgraph-js-http
  • Dgraph.NET

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:

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:

TypeError: Cannot read property 'toObject' of undefined

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