Following on from "How to update collection and increment hours for ISO date".
It seem that RoboMongo can't execute a query with an array filter:
This same query if find when executed through the Mongo shell though:
> db.collection.update({
... "results.score": {
... "$exists": true
... }
... }, {
... "$mul": {
... "results.$[result].score": 10
... }
... }, {
... "arrayFilters": [{
... "result.score": {
... "$exists": true
... }
... }],
... "multi": true
... })
WriteResult({ "nMatched" : 1, "nUpserted" : 0, "nModified" : 1 })
Looking at the logging in the Mongo server, it looks like the query is passed over correctly, but still fails:
D COMMAND [conn4] run command test.$cmd { update: "collection", updates: [ { q: { results.score: { $exists: true } }, u: { $mul: { results.$[result].score: 10.0 } }, multi: true, upsert: false } ], ordered: true, $db: "test" }

The logs from the shell are different:

I can't see anything that would imply that something is wrong though (other than the assertion failure of course).
- What's causing RoboMongo to fail where Mongo shell succeeds?
- Is there anything in these logs that tells me what's wrong?
