Bug: Visiting /v/posts crashes the backend #137

Closed appins closed 3 years ago

appins commented 3 years ago

Expected Behavior

Visiting /v/posts should either display a page of unfiltered results or display some error (400 bad request?). The backend should continue running normally.

Actual Behavior

The backend crashes. Stack trace:

panic: runtime error: index out of range [0] with length 0

goroutine 74 [running]:

@daved and @codegold79 (and some others) watched me produce this error on stream.
