(node:25375) DeprecationWarning: Mongoose: the isAsync option for custom validators is deprecated. Make your async va lidators return a promise instead: https://mongoosejs.com/docs/validation.html#async-custom-validators

[denzilgupta]

This is my code:

tags: {
type: Array,
validate: {
isAsync: true,
validator: function(value, callback) {
setTimeout(() => {
const result = value && value.minlength > 0;
callback(result);
}, 4000);
},
message: 'A course must have at least one tag'
}
}

when I try to insert a value into mongodb, I get the below warning:
(node:25375) DeprecationWarning: Mongoose: the isAsync option for custom validators is deprecated. Make your async va lidators return a promise instead: https://mongoosejs.com/docs/validation.html#async-custom-validators

I saw the documentation and they too have used a callback function.
Please help me solve this problem!

Node Version:
v10.16.3

Are you getting an error on this file? Cause it seems to look fine.
