Mail Schema:

var mail = new mongoose.Schema({
    globalId: {type: String, index: true, unique: true},
    from: {type: String, required: true},
    beginDate: {type: Date, required: true},
    endDate: {type: Date},
    source: {type: String},
    address: {type: String},
    subject: {type: String, required: true},
    text: {type: String},
    note: {type: String},
    files: [
        {
            fileName: {type: String},
            fileSize: {type: Number},
            fileType: {type: String}
        }
    ]
});

When I try to save new mail with endDate is null I have the following error

Mail validation failed: endDate: Cast to Date failed for value "null"

It looks like you are trying to save the schema with an invalid endDate.

If you do not want to save a date simply leave it out from the object. For instance all you need to provide for your schema at a minimum is:

const newMail = mail.create({
    globalId: "1234",
    from: "Jack",
    begineDate: new Date(),
    subject: "Random subject",
});

If you tried to do something like,

endDate: null

this will fail as it is expecting a Date() object or nothing at all.

How can I assign a null value to date field using mongo go driver , Time , you cannot set any value to it to end up MongoDB null value. Set default date when inserting document with time.Time field · Accesing  (You will not have endDate key in MongoDB) set endDate: undefined that will automatically be ignored. (You will not have endDate key in MongoDB) Set endDate: null not in String (You will have endDate key as null value) Below one will not work: var testObj = { ct: "null", // null as String value name: "Foo" } But this one will definitely work:

As you have mentioned that you are storing endDate as null as String. That will definitely fail because your schema expecting a date and you are storing String.

Multiple ways you can approach:

  1. Avoid endDate from JSON object. (You will not have endDate key in MongoDB)
  2. set endDate: undefined that will automatically be ignored. (You will not have endDate key in MongoDB)
  3. Set endDate: null not in String (You will have endDate key as null value)

Below one will not work:

var testObj = {
    ct: "null", // null as String value
    name: "Foo"
}

But this one will definitely work:

var testObj = {
    ct: null, // null as value
    name: "Foo"
}

Tested on below version:

MongoDB v3.2.18 Mongoose v4.10.8

Another point I want to add here is storing key: null will consume resources. If your requirement is not dependent on null values, I would like to use not to store a key in the database rather storing as null.

I have solved this by setting the default date to undefined. It will not show up on creation of your object. That is fine as it is now a frontend problem. If a key does not exist the frontend will default to undefined. If it remains undefined it will not be saved in your database. Avoid having a default null I have made that mistake too!

mail = {
  endDate: {
   type: Date,
   default: undefined
  }
}
