how to define an array of array of number/string (2d array)?

[grimmer0125]

Thanks for supplying this so great library.

in normal mongoose
I can define like this

const blogSchema = new Schema({
    data: [[Number]]
});

I have tried but failed

data: Type.array().of(Type.array().of(Type.string()))

How can I define this in ts-mongoose?

Following seems to be working:

Type.array({ required: true }).of(Type.array({ required: true }).of(Type.string())),

Also this:

Type.array().of(Type.array().of(Type.string())),

What type is returned for data?

Thanks. @lchimaru .

It just throws a runtime exception

The following writing method can works!

- Type.array().of(Type.array().of(Type.string()))
+ Type.array().of({})

My db data.
