### Apache Airflow version

2.7.0

### What happened

Actual Behavior:
Upon entering a keyword in the search bar, no search results are shown, and the UI remains unchanged. The search function seems to be non-responsive.
You can see in the address bar, `undefined` appears instead of valid value.

### What you think should happen instead

Expected Behavior:
When I use the search function in the Airflow UI, I expect to see a list of results that match the entered keyword. This should help me quickly locate specific DAGs or tasks within the UI.

### How to reproduce

Steps to Reproduce:
1. Log in to the Airflow UI.
2. Navigate to the "Connections" list view by clicking on the "Connections" link in the navigation menu or by directly visiting the URL: <your_airflow_ui_url>/connection/list/.
3. Attempt to use the search function by entering a keyword.
4. Observe that no search results are displayed, and the search appears to do nothing.
