BSONTypeConversionError on trying to decode Date from timestamp in MongoDB

[surajthomask]

We were trying to update the Vapor dependencies in our project, and encountered an issue with conversion of timestamp in MongoDB to Date objects. Version 8.0.1 works just fine, but updating to 8.0.6 breaks the decoding and throws the following error. {"reason":"BSONTypeConversionError<Optional<Primitive>>(from: Optional(695638132.716054), to: Foundation.Date)"}

An example model is given below;

          struct Item: Model {

            @Field var _id: ObjectId
            @Field var name: String
            @Field var updatedAt: Date

            init(name: String) {

                self._id = ObjectId()

                self.name = name

                self.updatedAt = Date()
            }
        }

v8.0.1 allows data insertion as well as retrieval without any issue. v8.0.6 breaks the data retrieval from the DB.

Would appreciate a quick look into this.

Hey @surajthomask,

Is your date stored as a Double in the database?

Hi @Joannis, Thanks for the response. As of 8.0.1, the framework was storing the date as double in the server on it's own. As far as I can see there were no custom handling of data type other than specifying the variable type to be Double in the model. When we updated the dependencies to 8.0.6, it started throwing this error.
