Cannot use AsyncioExecutor

[mecampbellsoup]

The Starlette docs indicate that I should import an "async executor" a la:

from graphql.execution.executors.asyncio import AsyncioExecutor

However this module graphql.execution.executors no longer seems to exist in graphql-core versions > 3.

How should one go about using graphql-core now (i.e. version 3+) with async executors? Or should I just use the core-legacy library? My async resolve_* queries are otherwise erroring as follows:

[Cito]

You should ask about this in the Starlette project. It seems Starlette supports only Graphene 2 which means GraphQL-Core 2 (legacy, not supported any more). The GraphQLApp class seems to be deprecated inside Starlette also.

The current GraphQL-core does not have have executors and uses async execution by default.

FYI Starlette has deprecated built-in GraphQL support. See #619
