Description

The /api/edges endpoint crashes with HTTP 500 when any traceroute record has route = None (malformed or incomplete packet).
A single such packet takes down the endpoint for all users until the service is restarted.

Traceback

File "/app/meshview/web_api/api.py", line 484, in api_edges
path = [tr.packet.from_node_id] + list(route.route)
^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'route'

Proposed fix

Add a guard before line 484:

if route is None or route.route is None:
    continue
path = [tr.packet.from_node_id] + list(route.route)

Notes

Fix applied on our instance and confirmed working.
