$push and $set in same MongoDB update

Question

I\'m trying to use MongoDB\'s Java driver to make two updates ($set and $push) to a record in the same operation. I\'m using code similar to the following:

Answer 1

My mongodb version is 3.4.20 and while using

db.collection.update({_id: pageId}, [{$push: {values: dboVital}}, {$set: {endTime: time}}]);

I received error

[thread1] Error: field names cannot start with $ [$push] :

To solve that error we can use:

db.collection.update({_id: pageId}, {$push: {values: dboVital}, $set: {endTime: time}});
