findById read empty arrays when the items are defined with a "_id" field about typegoose

[derchirurg]

I found out: do not define _id as prop. Just use it as property and it should work.

Thank you @derchirurg but your answer is not complete.
I tried to remove the _id definition field but:
if I save an _id as string I can't use that to find the recors and I can't load that field with typegoose using find or findbyid.

With other mongo client I can use that _id also when ai save it as ObjectID or as string because mongoose convert it automatically. So, I think this is a typegoose issue.

This is a problem for that records that you have to save before run the app for configuring something on the db. In that case is usefull to use a known _id (as string). But, when the app is running, is usefull use the automatic ObjectID generation.

I tried also this definition:

@tg.prop({ required: false, index: true}) _id: string | mongoose.Schema.Types.ObjectId;

but this solution cause an exeption:

In property _id: Object is not a primitive type nor a Typegoose schema (Not extending it).

@Ben305 this can be closed as "stale" & "fixed?" - no-one encountered this again since January 2018, and should be working with v6
