I am using the mongodb 3.5.5 with mongoose 4.9.8 and the Node.js version is 7.10, when I publish my app to production server, the error was happened, but in my develop environment is work.
How can I fix them?
The error message:
{ MongoError: The 'cursor' option is required, except for aggregation explain
at Function.MongoError.create (/data/deploy/disneynoq/webapp/node_modules/mongodb-core/lib/error.js:31:11)

ok: 0,
errmsg: 'The \'cursor\' option is required, except for aggregation explain',

codeName: 'FailedToParse' }
js code:
articleLikeSchema.statics.sumById = function ({id = ''} = {}) {
return this.model('ArticleLike').aggregate([
{ $match: { id: id } },
{ $group: { _id: '$id', count: { $sum: 1 } } }
]).then(sum => {
if (!sum || sum.length === 0) return Promise.resolve({count: 0})
else return Promise.resolve(sum[0])
})
}
The Mongoose execute command:
Mongoose: articlelikes.aggregate([ { '$match': { id: '1494606935' } }, { '$group': { _id: '$id', count: { '$sum': 1 } } } ], {})
