Invalid or incomplete introspection with async transport

[dysphie]

Hi, I seem to be having issues migrating from a blocking implementation to async. The migrated code raises an exception.

Original:

from os import getenv
from gql import gql, Client
from gql.transport.requests import RequestsHTTPTransport

query = gql('''
    query {
        user(username:"Test") {
            username
        }
    }
''')

if __name__ == '__main__':

    transport = RequestsHTTPTransport(
        url='http://api.aidungeon.io/graphql/',
        headers={'X-Access-Token': getenv('AIDUNGEON_TOKEN')}
    )

    client = Client(
        transport=transport,
        fetch_schema_from_transport=True,
    )

    result = client.execute(query)
    print(result)

Output:

{'user': {'username': 'Test'}}

Migrated

from os import getenv
from gql import gql, Client
from gql.transport.aiohttp import AIOHTTPTransport
import asyncio

query = gql('''
    query {
        user(username:"Test") {
            username
        }
    }
''')

async def main():

    transport = AIOHTTPTransport(
    url='http://api.aidungeon.io/graphql/',
    headers={'X-Access-Token': getenv('AIDUNGEON_TOKEN')}
    )

    client = Client(
        transport=transport,
        fetch_schema_from_transport=True
    )

    async with client as session:
        result = await session.execute(query)
        print(result)

asyncio.run(main())

Output:

TypeError: Invalid or incomplete introspection result. Ensure that you are passing the 'data' attribute of an introspection response and no 'errors' were returned alongside: None.

Not sure how to proceed. Thanks

Hi,

This is a duplicate of bug #92 It is solved with PR #94

@leszekhanusz I've cloned master and did 'pip3 install .', but still get

Invalid or incomplete introspection result. Ensure that you are passing the 'data' attribute of an introspection response and no 'errors' were returned alongside: None.

@leszekhanusz Your PR does not fix the same error when using the WebsocketsTransport transport

Just a note to others, or maybe I was just being dumb, but I was missing a / at the end of the graphql URL:

e.g.

transport = AIOHTTPTransport(url="https://api.octopus.energy/v1/graphql/") # works

vs

transport = AIOHTTPTransport(url="https://api.octopus.energy/v1/graphql") # does not work
