ryandutton opened a new issue, #30122:
URL: https://github.com/apache/airflow/issues/30122
### Apache Airflow version
Other Airflow 2 version (please specify below)
### What happened
In Airflow 2.3.3, when setting an environment variable such as
`AIRFLOW_VAR_ENVIRONMENT` to `testing` I am getting a Broken Dag error. The
error message is
```
Broken DAG: [/blah/file.py] Traceback (most recent call last):
File "/blah/environment.py", line 62, in _get_environment
return Variable.get('environment')
File
"/usr/local/autotrader/lib/python3.8/site-packages/airflow/models/variable.py",
line 138, in get
raise KeyError(f'Variable {key} does not exist')
KeyError: 'Variable environment does not exist'
```
I've checked the database and the variable is not set in there, which may be
the expected behaviour as it doesn't show in the UI which is expected. When I
run `airflow variables get environment` it does return the expected value,
however, in a dag running `Variables.get('environment') it doesn't get the
variable.
### What you think should happen instead
The expected behaviour would be that when running
Variables.get('environment') in a dag, that it would return the expected value.
### How to reproduce
Set a variable as an environment variable and try getting the variable in a
dag using `Variables.get('<ENV_NAME>'). This would result in a Broken Dag error.
