I changed it to 'Hero' => $this->manager->getType(StaticSchema::inst()->typeName(DBFile::class)),

yes that's right

'Hero' => ['type' => $this->manager... ]

back to this error

Did that now I got:

or are you not using any scaffolding?

huh.. can you debug why SchemaScaffolder isn't adding it in registerFixedTypes?

no, it should be called in SchemaScaffolder::addToManager.. can you debug that?

am getting it run 3 times

ohhhhh

Your type creator is run before that is called

i wonder if you can put your fields in a closure

function { return ['ID' => ['type' ...] ] } etc..

mmmmm this is currently my function

public function fields()
    {
        $courseConnection = Connection::create('Topics')
            ->setConnectionType(function () {
                return $this->manager->getType('Topic');
            })
            ->setDescription('A list of the Topics')
            ->setSortableFields(['ID', 'Title']);
 
        return [
            'ID' => ['type' => Type::nonNull(Type::id())],
            'Title' => ['type' => Type::string()],
            'Estimate' => ['type' => Type::string()],
            'Audience' => ['type' => Type::string()],
            'Content' => ['type' => Type::string()],
            'Hero' => ['type' => $this->manager->getType(StaticSchema::inst()->typeName(DBFile::class))],
            'URLSegment' => ['type  ' => Type::string()],
            'Topics' => [
                'type' => $courseConnection->toType(),
                'args' => $courseConnection->args(),
                'resolve' => function ($object, array $args, $context) use ($courseConnection) {
                    return $courseConnection->resolveList(
                        $object->Topics(),
                        $args,
                        $context
                    );
                }
            ]
        ];
    }

so my fields function was already as you suggested

return function () {
            return [
               'ID' => ['type' => Type::nonNull(Type::id())],

Error: Course fields must be an object with field names as keys or a function which returns such an object.

fark

it's almost like fixed_types needs to be a config property of Manager, not SchemaScaffolder.

Well I could just scaffold the Course which worked previously

I was looking at adding in my own custom fields to the graphql response.

eg. I want to calculate the progress of a course and add it as a field into the Course response

Thanks mil for all your help @unclecheese

Yesssss!

So am I 😂

ah, right

i often wonder if we could expose those through docblocks
