(I created an Apache JIRA account to try report this there, but in the
Create Issue dialog box the Airflow project was not among the many options.)
Airflow version: 1.10.9
Description: A rebuild of the docker image we use to run Airflow upgraded
the version of SQLAlchemy to 1.3.16, which causes the following exception
when starting the airflow webserver:
Traceback (most recent call last):

Specifying SQLAlchemy <= 1.3.15 in the requirements.txt file we use to
build the docker image fixes the issue. Our requirements.txt file now looks
like this:
apache-airflow[crypto,mysql,slack] == 1.10.9
pendulum == 1.4.4
requests >= 2.20.0, < 3
SQLAlchemy <= 1.3.15
Our Dockerfile is based on python:3.7-slim
Hopefully that lets somebody reproduce the issue. Let me know if there's a
way I can submit this bug on JIRA instead, or if there's anything else I
can do to help.
