Debug toolbar with batching #786
Description
Describe the Bug
I setup the debug toolbar as of: https://strawberry.rocks/docs/django/integrations/debug-toolbar
It works... until I enable batching.
It seems like batching breaks the debug toolbar.
You’ve hit a Strawberry-Django Debug Toolbar middleware bug/limitation: batched GraphQL responses are a JSON array, but the middleware assumes a single JSON object and then tries payload["debugToolbar"] → TypeError: list indices must be integers….
