Description

Apache Airflow version

3.1.3

If "Other Airflow 2/3 version" selected, which one?

No response

What happened?

This is still an issue on 3.1.3

I have this setup and I get the errors below still

(venv) ekaram@9TVW494:/home/bot/ETL$ airflow connections test Maria_DB_tester Retrieving connection: 'Maria_DB_tester'

Testing...

Connection failed! The conn_id Maria_DB_tester isn't defined

even though that connection is in the list (venv) ekaram@9TVW494:/home/bot/ETL$ airflow connections list --conn-id Maria_DB_tester id | conn_id | conn_type | description | host | schema | login | password | port | is_encrypted | is_extra_encrypted | extra_dejson | get_uri ===+=================+===========+=============+=======================+========+========+==========+======+==============+====================+==============+================================================== 2 | Maria_DB_tester | mysql | None | ProdDb.westernexp.com | None | ekaram | MariaDB | 3306 | True | True | {}

In the UI i only get a red wifi with crossbeam across it

What you think should happen instead?

it should tell me if the connection succeeded or not

How to reproduce

Define a connection string

Try to to test the connection either through the UI or cli. Neither work

Research direction
The issue reports that 'airflow connections test' fails with 'conn id isn't defined' even though the connection exists in the list. The bug likely lies in the CLI command implementation (airflow/cli/commands/connection command.py) or the underlying connection retrieval logic. Investigate how the connection ID is resolved during the test command. Check the UI endpoint for testing connections as well. Look for any recent changes that might have introduced a regression. Comments in the issue may contain additional clues.
