micaelamaria opened a new issue #20820:
URL: https://github.com/apache/airflow/issues/20820
### Apache Airflow version
2.2.1
### What happened
The UI doesn't display my connections list. I run the scrypt below, and
copied the fernet key in my airflow.cfg
#from cryptography.fernet import Fernet
#fernet_key = Fernet.generate_key()
#print(fernet_key.decode())
Even after pasting the generated key I get:
File "/usr/local/lib/python3.8/dist-packages/airflow/models/connection.py",
line 238, in get_password
return fernet.decrypt(bytes(self._password, 'utf-8')).decode()
File "/usr/local/lib/python3.8/dist-packages/cryptography/fernet.py", line
194, in decrypt
raise InvalidToken
cryptography.fernet.InvalidToken
I am also having connection refused: "AirflowNotFoundException(f"The conn_id
`{conn_id}` isn't defined")" and "ERROR - Unable to retrieve connection from
secrets backend (MetastoreBackend)."
### What you expected to happen
It was working just fine, and overnight airflow stopped working and throwing
this error. I redefined the connections, yet still.
### How to reproduce
I did it as follows: I created a new dag that only prints "hello" to a
postgres database and used a connection I had already (one that worked just
fine the day before), and the error comes up.
