This is because decodestring has been deleted since python3.9.

The easiest way to solve this problem is to downgrade python to 3.8.

If you are using docker, modify the first line of the dockerfile to FROM python:3.8, and rebuild the docker image.

Or you can upgrade the elasticsearch dependency library if you understand what you are doing.
