Mongodb database backup from localhost

Question

I am using "mongodb-backup" plugin for take database backup.

Database connection url link:

var _dbConnectionURL = 'mongodb://uname:password@LocalIpAddress:port/databasename?authdb=admin';
mongoose.connect(_dbConnectionURL);

This code for connect nodejs with mongodb. It is working well.

Now i try to take backup from nodejs

var backup = require('mongodb-backup');
backup({
    uri: _dbConnectionURL,
    root: './Media/MongoDB_BK',
    tar: 'sample.tar',
    callback: function (err) {
        if (err) {
            console.error(err);
        } else {
            console.log('finish');
        }
    },
});

Error:

Answer 1

Try using authsource instead of authdb

var _dbConnectionURL = 'mongodb://uname:password@LocalIpAddress:port/databasename?authsource=admin';

or try setting authdb in the options parameter

backup({
    uri: _dbConnectionURL,
    root: './Media/MongoDB_BK',
    tar: 'sample.tar',
    options: {
       authSource: 'admin'    
    }
});
