Unable to find container id

While redeploying CMS XCaches (docker behind the scenes), noticed the following failure:
```
2025-05-21 11:17:54,034 [app.py:828] [ERROR] Exception on /api/janus/controller/stop/121 [PUT]
Traceback (most recent call last):

return session_manager.stop_session(id)
File "/opt/janus/janus/api/session_manager.py", line 382, in stop_session
cid = s['container_id']
KeyError: 'container_id'

During handling of the above exception, another exception occurred:

It was happening anytime I do create/delete on the Janus Web UI. It looks like the following change broke it (especially inside the session_manager.py lines 310 and 381): https://github.com/esnet/janus/commit/62e5ab5aa0e178e1497d53555668102f50e2f594#diff-4e55cea4f0ac47f60cf363e91f6d7f46fb7b174417cc829cff5e01e9e9b85764R343 . I edited Janus (for Xcaches) directly with the following change:
```
310,314c310
< cid = s.get("container_id")
< if not cid:
< log.warning(f"Skipping service with no cotnainer_id: {k} {s}")
< error = True
< continue
---
> cid = s["container_id"]
381,383c377
< cid = s.get('container_id')
< if not cid:
< log.warning(f"Skipping service with no container_id: {k} {s}")
---
> cid = s['container_id']

```
With the following change, I was able to proceed and launch XCache containers.
