Airflow 2.9.3: Unable to parse the connection string

[nitinmahawadiwar]

Apache Airflow version

Other Airflow 2 version (please specify below)

If "Other Airflow 2 version" selected, which one?

2.9.3

What happened?

We are experiencing Azure Blob connection string parse error on Airflow 2.9.3 (self hosted, deployed through official helm chart). The same code is working fine on Auzre Managed Airflow 2.6.3.
Both environments are using Python 3.8

Broken DAG: [DAG Path] Traceback (most recent call last): File "/home/airflow/.local/lib/python3.8/site-packages/azure/storage/blob/_blob_service_client.py", line 195, in from_connection_string account_url,secondary,credential=parse_connection_str(conn_str,credential,'blob') File "/home/airflow/.local/lib/python3.8/site-packages/azure/storage/blob/_shared/base_client.py", line 387, in parse_connection_str conn_str=conn_str.rstrip(",") AttributeError: 'NoneType' object has no attribute 'rstrip'

The code to get connection's details is as follow:
We read a Variable. That variable stores the connection details (conn_id). This connection id exists in the Connections list.

The Test connection was successfull from web ui.

My query is: Are there any changes from airflow 2.6.3 to airflow 2.9.3 over connection details (conn string, url format etc)

What you think should happen instead?

The connection should work from the DAG as Test connection was successful.

How to reproduce

Create a Azure Blog Storage connection type with all details, Test the connection from web UI.

Try to load connection from source code.

Operating System

Debian GNU Linux 12

You need to debug it. There were likely few 100s if not more changes between those versions. You can read release notes if you want to spend time on it, or someone who you ask here would have to do it, becasue there is no way to know it by heart.

And it's not clear where the error is - looks like you are getting somewhere None. Maybe because you have a typo or maybe something is not accessing the right db or smth. You need to debug it.

Converted to a discussion - as this is not clear whether it's airflow issue.
