One of my colleagues ran into this testing the JSON Facet API. A malformed
JSON Facet API range query seems to get a NPE and then devolves into saying
no live servers to handle the request. It looks like the
FacetRangeProcessor should check the inputs before trying to getField. Does
this seem reasonable?

The problematic query:

json.facet={price:{type:range,start:0,end:600,gap:50}}

The fixed query:

json.facet={prices:{field:price,type:range,start:0,end:600,gap:50}}

The stack trace:
