Event service refuses to serve JSON

[pevans-gfz]

Today a request for events from the "geofon" service in WebDC3, as JSON like this:

http://eida.gfz.de/webdc3/wsgi/event/geofon?start=2025-07-01&end=2025-07-02&format=json

receives an immediate 502 Bad Gateway response. It should work like the "geofonfdsnws" service in WebDC3:

http://eida.gfz.de/webdc3/wsgi/event/geofonfdsnws?start=2025-07-01&end=2025-07-02&format=json receives text/plain with 12 events.

and like these with format=text

http://eida.gfz.de/webdc3/wsgi/event/geofonfdsnws?start=2025-07-01&end=2025-07-02 receives text/plain, but with 3 events
http://eida.gfz.de/webdc3/wsgi/event/geofon?start=2025-07-01&end=2025-07-02 receives text/plain, but with only 2 events (though that is another issue!)

Aside:

• The "geofon" service output (with format=json) matches what the front end displays for catalog service "GFZ", showing 12 events.
• The "geofonfdsnws" service output (with 502 error) matches the front end's behaviour for catalog service "GFZ eqinfo", showing "Failed to get events: ... [Bad Gateway]" on the console tab.
