field "cars" not found in type: 'query_root' ???????????????

So my query runs some times, but most of the time I get this error come back and I have no idea why.

I've set all the permissions etc so it is crazy why this is happening?

If I go to Graphiql I get the same error if I enable Relay API, but then I can't fetch the list and aggregate as it only provides the cars_connection query.

I'm SUPER confused as to why this isn't working.

Start by reproducing the query in GraphiQL with the Relay API both enabled and disabled, and compare the available fields on query_root. Check how the cars and cars_connection fields are exposed, then verify the fix or explanation against the original query and aggregation request.
