Question 115547 in Mongodb Question posted in
The official documentation can be found here.

Mongodb – Does empty string match mongo db schema of required?

I have a mongodb schema like below.

const DemoSchema: Schema = new Schema({
  demoProperty1: { type: String, required: true }
});

I create a document with syntax in node js server like below.

const savedDemo = await this.demoModel.create({demoProperty1:""});

Why it is returning error message

UnhandledPromiseRejectionWarning: ValidationError:

    Yes I have fix this issue by trial and error. Empty string is not eligible for mongodb required schema, Took me 5 hours to figure it out. I can just passed in any string but not an empty string to make it valid and passed without any error.

    From the documentation:

    // Use this to allow empty strings to pass the `required` validator
mongoose.Schema.Types.String.checkRequired(v => typeof v === 'string');
