How to reproduce it:
From official latest docker image:
FROM apache/airflow:1.10.13-python3.8
RUN pip install --no-cache-dir --user -U apache-airflow==1.10.14rc1 airflow-exporter==1.3.0
Anything else we need to know:
I guess it's related to recent changes in #12694. I have little knowledge on importlib, but it seems like there's no module nor module_name in importlib.metadata.EntryPoint.
