GitHub API: Server did not return a GraphQL result

[BElluu]

Hello,

I want to get some information from Github API. I using your gql. When I do simple request I got "Server did not return a GraphQL result". Do you have any idea what I doing wrong?

from gql import gql, Client, AIOHTTPTransport

URL = "https://api.github.com/graphql"

transport = AIOHTTPTransport(url=URL, headers={'Authorization': 'MY_TOKEN'})

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

query = gql('''
query {
  search(query: "test", type: ISSUE, first: 20) {
    nodes {
      ... on Issue {
        id
        bodyHTML
        title
        url
        closed
      }
    }
  }
}
''')

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

venv/lib/python3.8/site-packages/gql/transport/aiohttp.py", line 161, in execute
raise TransportProtocolError("Server did not return a GraphQL result")
gql.transport.exceptions.TransportProtocolError: Server did not return a GraphQL result

I added some debugging info and tried to use your code (with an invalid token) and I received:

{'message': 'This endpoint requires you to be authenticated.', 'documentation_url': 'https://docs.github.com/v3/#authentication'}

Which is not valid because it does not contain either a data or and errors key in the json. So I received the same error.

I will add more debugging possibilities, but for now, could you please add the following line:
print(f"result={result!r}")
in the gql/transport/aiohttp.py file, just after the line:
result = await resp.json()

So that we can know if you have the same problem.

Note: I created a token to test this and now this works for me with your code.

The only modification I made is to add "bearer" before the token:

transport = AIOHTTPTransport(url=URL, headers={'Authorization': 'bearer MY_TOKEN'})

I don't know if it is the correct place to report issues to GitHub but I created a post here

@leszekhanusz that's it. I missed "bearer" before my token. I added that and I got correct response. Thank you!
This error message was a bit confusing to me.

With PR #155 the message should be more clear:

    raise TransportProtocolError(
gql.transport.exceptions.TransportProtocolError: Server did not return a GraphQL result: No "data" or "error" keys in answer: {"message":"This endpoint requires you to be authenticated.","documentation_url":"https://docs.github.com/v3/#authentication"}
