The main meaning is that in order to fight aws, es no longer supports the apach 2.0 open source protocol in the new version.

Therefore, it is necessary to reduce the dependency version of the es client of the python project or adopt the open source version of opensearch newly pulled by aws. However, opensearch can not be used in the production environment

So modify the es version of the specified project in pipfile.rch can not be used in the production environment

Restart the build, the problem is solved!
