Description

I tried to create document but it gave error Error - ValidationError: Description: Path Description is required

Steps to Reproduce

Model

let Order = new mongoose.Schema({
  Description: {
        type: String,
        required: true
    },
};
let data = {Description : description ?? ""}; 
let order = new SchemaOrder(data);
//error
let newOrder = await order.save();

Expected Behavior

No response

I’m guessing it’s because your document is passing in an empty string for description. A required string means it has a value (and the empty string is not considered a value). You have a few options I think including.

1. https://mongoosejs.com/docs/api/schematype.html#SchemaType.checkRequired() (You can change the behavior of that check globally)
2. What we’ve done at my company for these is make it not required and put in a default of ‘’ in th schema so that it always gets a value.

probably other solutions too but those are the two main ones I know about.

I agree with @sean-daley . I guess what you're looking for is default: "" instead of required: true

My question is. In the line let data = {Description : description ?? ""}; , where does the identifier 'description.' Moreover, you haven't declared any path in the schema called 'description.'

Empty string "" fails the required check for strings in Mongoose by default. If you want to allow empty strings to pass required validator for strings, run the following code when your program starts.

// Allow empty strings to pass `required` check
mongoose.Schema.Types.String.checkRequired(v => v != null);
