I found one area that this doesn't handle properly at all, and that's
deleting documents where the ID cannot be found. The reason your patch fails
there is that the check around the declaration of `boolean errors` ~ line 353
doesn't expect ElasticSearch to treat this as an inconsequential problem
instead of an error. See this JSON I got in the debugger when running a flow:
{
"took": 346,
"errors": false,
"items": [{
"delete": {
"found": false,
"_index": "events",
"_type": "event",
"_id": "abcd_1509454409510",
"_version": 1,
"result": "not_found",
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"status": 404
}
}]
}
I try indexing some really bad (syntatically valid JSON that is not what
Elastic expects) and see if that goes to the error queue.
My guess is that an update on a missing document ID will return the same
sort of JSON as the delete.
