Error creating a Schema with a field of type file in NodeJs

    const mongoose = require('mongoose');
const {Schema} = mongoose;


const empleado_schema = new Schema({
    dni:{type:String,required:true, unique:true},
    nombre:{type:String, required:true},
    apellidos:{type:String, required:true},
    departamento:{type:String, required:true},
    sueldo:{type:String, required:true},
    fecha_nacimiento:{type:Date, required:true},
    imagen_perfil:{type:File,required:true}
});


module.exports = mongoose.model('tbEmpleadoss',empleado_schema);

Everything is fine until I insert the field image_profile which gives me the following error:

 imagen_perfil:{type:File,required:true}
                    ^

ReferenceError: File is not defined
