bmanan7 opened a new issue, #57864:
URL: https://github.com/apache/airflow/issues/57864
### Apache Airflow version
3.1.1
### If "Other Airflow 2/3 version" selected, which one?
_No response_
### What happened?
In Airflow 3.x the execution API route GET
`/execution/connections/{conn_id}` treats the connection ID as a FastAPI path
segment. Conn IDs containing / (e.g., dev-env/project-name) are not URL encoded
before the request, so Starlette splits them into multiple segments and returns
404 even though the connection exists.
airflow connections get (CLI) still works because it bypasses the execution
API, causing a mismatch between CLI and Task SDK behaviour.
Apart from this one will also get`AirflowNotFoundException` when the secret
value is defined as `{"username":"[email protected]", "password":"****"}`
however we don't get the error if we define secret value as show below:
```
{
"conn_type": "http",
"login": "[email protected]",
"password": "***",
"host": "https://api.somedomain.com";,
"port": 443,
"extra": "{\"verify_ssl\": false}"
}
```
it looks like without `conn_type` defined it doesn't work in Airflow3?
### What you think should happen instead?
- `/` in secret name should be accepted.
- Either `conn_type` should be marked as compulsory and documentation should
be updated to reflect this or airflow should accept a secret without `conn_type`
### How to reproduce
- Start an Airflow 3.x environment.
- Inside the scheduler container, create a connection whose ID contains /.
Example script:
```
python3 - <<'PY'
from airflow import settings
from airflow.models.connection import Connection
conn = Connection(conn_id="dev-env/project-name", conn_type="http",
host="example.com")
session = settings.Session()
session.merge(conn)
session.commit()
PY
```
- Add a DAG with a task that calls
BaseHook.get_connection("dev-env/project-name") .
- Trigger the DAG. The task fails and worker logs show a 404 from GET
/execution/connections/dev-env/project-name.
- (Optional sanity check) Running airflow connections get
`dev-env/project-name` -oyaml still works because it bypasses the execution API.
