SystemOfaDrow opened a new issue #21657:
URL: https://github.com/apache/airflow/issues/21657
### Apache Airflow version
2.2.3 (latest released)
### What happened
We use credstash to set/retrieve passwords. While trying to upgrade from
Airflow v2.2.1 to v2.2.3, we started getting failures connection to the
meta-database and ended up tracking the issue down to an additional new line
character being inserted at the end of the connection string.
