GraphQLError unknown type

[jimshepherd]

Trying to get a pyramid / sqlalchemy / graphene server to work with a Relay example:
relay modern todo example
but am receiving an error when running a mutation (queries work fine):

GraphQLError('Unknown type "RenameTodoInput".',)

relevant schema:

class Todo(SQLAlchemyObjectType):
    class Meta:
        model = TodoModel
        interfaces = (relay.Node, )


class RenameTodo(relay.ClientIDMutation):
    class Input:
        text = graphene.String(description='Text', required=True)
        id = graphene.Int(description='Todo Id', required=True)

    todo = graphene.Field(Todo)
    ok = graphene.Boolean()

    @staticmethod
    def mutate_and_get_payload(root, args, context, info):
        todo_id = args.get('id')
        todoModel = Todo.get_query(context).first()
        todoModel.text = args.get('text')
        todo = Todo(todoModel)
        ok = True
        return RenameTodo(todo=todo, ok=ok)


class Mutations(graphene.ObjectType):
    renameTodo = RenameTodo.Field()

the Relay mutation:

const mutation = graphql`
  mutation RenameTodoMutation($input: RenameTodoInput!) {
    renameTodo(input:$input) {
      todo {
        id
        text
      }
    }
  }
`;

the actual request:
{"query":"mutation RenameTodoMutation(\n $input: RenameTodoInput!\n) {\n renameTodo(input: $input) {\n todo {\n id\n text\n }\n }\n}\n","variables":{"input":{"text":"Do something","id":"QmVlcjox"}}}

schema.introspect() seems to indicate that the type is being created:

            "types": [
                ...
                {
                    "kind": "INPUT_OBJECT",
                    "name": "RenameTodoInput",
                    "description": null,
                    "fields": null,
                    "inputFields": [
                ...

I have tried creating a custom RenameTodoInput class, but still received the same error.

Versions:
graphene (1.4.1)
graphene-sqlalchemy (1.1.1)
graphql-core (1.1)
graphql-relay (0.4.5)

Any help is appreciated.

    class Input:
        text = graphene.String(description='Text', required=True)
        id = graphene.Int(description='Todo Id', required=True)

This schema say you can use only:

  mutation RenameTodoMutation($textValue: String!, $idValue: Int!) {
    renameTodo(text: $textValue, id: $idValue) {
      todo {
        id
        text
      }
    }
  }

For custom types you need use http://docs.graphene-python.org/en/latest/types/scalars/

Hi @jimshepherd . We're currently going through old issues that appear to have gone stale (ie. not updated in about the last 6 months) to try and clean up the issue tracker. If this is still important to you please comment and we'll re-open this.

Thanks!
