Cannot return null for non-nullable field about graphql-doctrine HOT 5 CLOSED

My bad, I was missing

GraphQL::setDefaultFieldResolver(new DefaultFieldResolver());

Regards

from graphql-doctrine.

The default resolver provided by this lib should be able to resolve getters of objects in an array. But it seems you are not giving an array but a collection of some sort. Maybe an ArrayObject ?

You should double check that and either write your own resolver or return a real array.

I will check but put in this

return [$tape->getLanguages()->current()]

instead of

return $tape->getLanguages()->toArray()

Also output same error.

Thanks!

This is a bit of a blind guess, but you should try validating your schema (in your unit tests) with the \GraphQL\Type\Schema::assertValid() method. Just to be sure your schema makes sense.
