aiohttp.client_exceptions.ClientConnectionError: Connection closed when a response is significantly large: https://pastebin.com/NmmnqhVt though I am new to async stuff so likely doing something wrong...
this is because you move response out of session context and session closes connection
Yes, I see.
First snippet uses aiohttp incorrectly, I don't think we need fix our code.
Reading response after session closing is mistake.
Well, we could raise another explicit exception like RuntimeError but I doubt if we need it.
We have to raise exception, otherwise it is very hard to find source of the problem especially for developers new to aiohttp
