I am trying to update a mongodb document by specifying _id field for the query match. I am using mongodb output component.
I am not able to specify the query criteria as below

{"_id" : ObjectId("579c18b47f34b4330f85a981")}

Instead the query is getting created as

{"_id" : "579c18b47f34b4330f85a981"}

with this query is not finding the document, and the update operation fails with the error No fields to update have been specified for modifier update operation!

am getting the id to be passed as a string from the previous step, and setting _id as the match criteria in the "Mongo Document Fields" tab.
