Generator yields data but resolver doesn't always receive it.

[LaraEzarik]

I am working on an issue where intermittently data isn't getting through to my resolver from the source/generator. The only info I have found with a similar result is python/cpython#74956 but this was fixed in python 3.8 that I am using.

I am a little lost here I have tried wrapping the generator in a try except block but nothing is thrown and the I put pre and post yield prints of my data in so I can see if it gets sent one in the generator and one in the resolver this is where I see that the generator gets all the data but the resolver doesn't.

Bellow I have attached a sample of the code being used and another important thing to mention is that I am running about 25 of these that could be contributing to the issue in some way.

from ariadne import SubscriptionType

subscription = SubscriptionType

@subscription.source('data')
async def data_generator(obj, info):
    while True:
        data = await queue.get()
        yield data

@subscription.field('data')
def data_resolver(data, info):
    return data
