I think the OUT node for node-red-node-mongodb (which is provided with the extra nodes package) should provide an output, so we can process the status of the query (Did it fail ? Did it succeed ? When ?)
Simple real case : I'm exposing an HTTP endpoint updating a document in a mongo DB. As of right now, I have no means to send the HTTP response WHEN the query is done, or to provide details on the success of the query in the HTTP response. My only option is to send a HTTP 200 when the HTTP endpoint is called, meaning I cannot send an error response when/if the node fails.
I'm willing to implement this, but I was suggested to post here before making a pull request.
Have a good day
