Cast to date failed for a $gte filter

Do you want to request a feature or report a bug? I want to report a bug

What is the current behavior? I have the following piece of code:

await Connections.find({ connections: { discord: { expires: { $gte: new Date() } } } })

with connections having the following model:

usersdb.model(
	"connections",
	new mongoose.Schema({
		userId: { type: String, unique: true },
		connections: {
			type: new mongoose.Schema({
				discord: {
					type: new mongoose.Schema({
						expires: { type: Date },
						token: { type: String },
						refreshToken: { type: String }
					})
				}
			}),
			default: () => ({})
		}
	})
)

Running that, gives me the following error: CastError: Cast to date failed for value "{ '$gte': 2022-04-10T23:04:34.662Z }" (type Object) at path "expires" for model "connections" (Full error available here)

What is the expected behavior? The code would run fine with no errors at all and return the documents matching the filter query.

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that “latest” is not a version. Node.JS - 16.10.0 Mongoose - 6.2.10 MongoDB - 5.0.6

Incorrect query syntax. You should query by expires.moment instead as shown below.

console.log(await Test.find({'expires.moment':{$gte: date}})

The MongoDB server interprets Test.find({expires:{moment:{$gte: date}}}) as “find all documents where expires is exactly equal to the object { moment: { $gte: Date('2022-04-11T20:17:45.481Z') } }”. In general, you should use dotted path names instead of nested objects for queries.

This worked for me, thanks 😃
