[DRF][Django][Github Action] I got 502 error from github actions workflows

Question

I replaced some sync view class with async view class and async serializer class in my api server.

what I used the class that is inherited for asynchronous is from here

And when I deployed it through a github actions(with zappa),

I got the following error from github actions

Error: Warning! Status check on the deployed lambda failed. A GET request to '/' yielded a 502 response code.

...

Error: Process completed with exit code 1.

I still haven't been able to solve it.

I think this error is caused by the async view class,

because the only change I made was to create an asynchronous view class and async serializer class.

Is there any solution?
