### What happened
After upgrading to Airflow **3.1.0** and the Git provider **0.8.0**, I
started seeing errors in the logs when DAG bundles are refreshed.
The error message is:
```
Sep 27 07:37:21 fondor airflow[1695637]: Traceback (most recent call last):

Sep 27 07:37:26 fondor airflow[1695637]: [2025-09-27T11:37:26.687228Z]
{manager.py:510} ERROR - Error initializing bundle thehub_git_repo: Connection
git_dags_bundle doesn't have a host url
```
This happens systematically after the upgrade and prevents the bundle from
initializing properly.
### What you think should happen instead
The Git bundle should initialize successfully using the configured Airflow
connection.
When the scheduler refreshes DAG bundles, the `git_dags_bundle` connection
should be resolved properly, and the repository `thehub_git_repo` should be
cloned or updated without raising an exception about a missing host URL.
In short: the bundle should load the DAGs normally after the upgrade,
without errors in the logs.
### How to reproduce
Configure Airflow with the following `airflow.cfg` snippet:
```
[dag_processor]
dag_bundle_config_list = [
{
"name": "dags-folder",
"classpath": "airflow.dag_processing.bundles.local.LocalDagBundle",
"kwargs": {}
},
{
"name": "thehub_git_repo",
"classpath": "airflow.providers.git.bundles.git.GitDagBundle",
"kwargs": {"tracking_ref": "main",
"subdir": "dags",
"git_conn_id": "git_dags_bundle"
}
}
]
```
Then create a connection named `git_dags_bundle` in Airflow, with the
**repository URL properly configured** along with authentication details.
After restarting the scheduler with this setup, the error appears in the
logs.
### Anything else
This configuration was working correctly with Airflow 3.0.6
