Mongodb findAndModify node js

Following code gives me exception in node js saying: "need remove or update"

var args = {
                query: { _id: _id },
                update: { $set: data},
                new: true,

                function (err, results) {
                    if (err) {
                        return callback(err);
                    } else {
                        callback(null, results);

Not able to figure out the issue as I have specified the update operation.


The syntax is different in the node driver than for the shell, which is the syntax you are using.

    { _id: _id },     // query
    [],               // represents a sort order if multiple matches
    { $set: data },   // update statement
    { new: true },    // options - new to return the modified document
    function(err,doc) {


There is a separate function for .findAndRemove()

As the documentation for the remove parameter of the findAndModify function states:

remove: <boolean>: Must specify either the remove or the update field. Removes the document specified in the query field. Set this to true to remove the selected document . The default is false.

The default value is false so you don't have to provide it at all.

I believe the issue is that you are supplying both update and remove parameters. Try removing the remove parameter.
