https://github.com/apache/couchdb-couch/pull/229
@kxepal : To get the format that we want above, I'm catching the throw from
an invalid input, and then forcing couch_query_servers to return
```{builtin_reduce_error, Reason, Value}```. Then, I bubble up that return
value and finally modify the message here:
https://github.com/apache/couchdb-couch-mrview/blob/master/src/couch_mrview_http.erl#L431
with
```
row_to_json({builtin_reduce_error, Reason, Value}) ->
Obj = {[{error, builtin_reduce_error}, {reason, Reason}, {caused_by,
Value}]},
?JSON_ENCODE(Obj);
```
However, maybe I'm not approaching this correctly since I am still confused
with: "You'll have to crash if error happened or you'll be forced to process
the error field correctly." Can you clarify a bit?
Tomorrow, I'm going to test the scenario with a map function errors so I
can better understand what's going on.
