GraphQL service does not support interfaces about graphql

[simstern]

I got help on this one recently from @johannessteu , and I still owe an update on the readme on how to do that :-)

You have to simply implement a NodeResolver implenting the __resolveType($entity) function to return the type.

For your case that would look something like this:

class NodeResolver implements ResolverInterface
{
    public function __resolveType(entity): string
    {
        // TOOD: return different type names for different implementations
        return 'CustomerAccount';
    }
}

Hope that helps.

@johannessteu @robertlemke I have the same error ...

final class VideoResolver implements ResolverInterface
{
    public function __resolveType($entity): string
    {
        return 'Movie';
    }
}

Error: Type "Video" is missing a "__resolveType" resolver

It was a configuration my resolver was not loaded correctly, everything works fine now

[dfeyer]

final class VideoResolver implements ResolverInterface
{
    public function __resolveType($data, $context, ResolveInfo $info): ?string
    {
        return match (get_class($data)) {
            MovieCollection::class => 'MovieCollection',
            Movie::class => 'Movie',
            TvShow::class => 'TvShow',
            TvShowSeason::class => 'TvShowSeason',
            TvShowEpisode::class => 'TvShowEpisode',
            default => null
        };
    }
}

My final resolver looks like this
