Issue getting GraphQL to work

Silverstripe Version: 4.3

Question:

I have setup GraphQL with an empty config and as far as I can tell I should be getting a result for the query:
/graphql/?query={__schema{types{kind+name+description}}}

I have set up the route with

SilverStripe\Control\Director:
   rules:
     'graphql': '%$SilverStripe\GraphQL\Controller.default'

but all I get back is an error - “Schema query must be Object Type but got: NULL”

The route /admin/graphql is working and gives me the expected result

I have obviously missed something pretty basic, so if anyone can point me in the right direction it would be appreciated

answered in slack but to follow up:
I just have a test project set up and I found this:

  • just setting the director rule (route) is not enough - it gives the same error
  • as soon as I added a type to the scheme eg
SilverStripe\GraphQL\Manager:
  schemas:
    default:
      scaffolding:
        types:
          Page:
            fields: [ID, Title, Content]
            operations:
              read: true
              create: true

it works… so maybe the schema can’t be empty?

Haha, snap.

Thanks a lot, what little hair I have is now intact

It seems that you can’t run it with no setup at all. There needs to be at least one type set up, e.g.:

SilverStripe\GraphQL\Manager:
  schemas:
    default:
      scaffolding:
        types:
          Page:
            fields: [ID, Title, Content]
            operations:
              read: true
              readOne: true
