Flow pod panics when returning event results

[jalfvort]

Describe the bug
Flow pod panics when calling the events api with no queries or a bad query.
UPDATED: It has nothing to do with queries. A panic happens when events.results is not empty. So offset=8 would run fine if there were less then 8 total results, but offset=0 would fail if there was atleast 1 result.

• Runs fine: curl http://localhost/api/namespaces/fvff/events?offset=8
• Causes panic curl http://localhost/api/namespaces/fvff/events?bad=8
• Causes panic curl http://localhost/api/namespaces/fvff/events

To Reproduce
Steps to reproduce the behavior:

1. Run curl http://localhost/api/namespaces/NAMESPACE/events
