Hey @aimananees sorry for the late answer to the PR. Why was multidict added to the PR? Is it something we need to upgrade docker?

[aimananees]

Hi @FabioRosado!
While I was trying to build the docker image, I was getting the following error:
Command "/usr/local/bin/python -u -c "import setuptools, tokenize;file='/tmp/pip-install-bk0tb4l6/multidict/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-record-ll9mdz1k/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-install-bk0tb4l6/multidict/
The command '/bin/sh -c pip3 install --no-cache-dir .' returned a non-zero code: 1

I was able to debug this error by adding multidict in requirements.txt

Ah sorry I should have read the issue and I would know why haha been awake since 3 am sorry for this.

All checks have passed and I was reading about the multidict and it seems its one dependency of aiohttp (I think the newer versions tho?). I will merge this changes now, thank you so much for working on this.
