Why is the "name" property missing in the error from Mongoose?

Question

MongoDB

Good afternoon. Trying to do normal error handling on a server connected to Mongo. To do this, I need to recognize errors related to the DB itself. For example, when I try to get an item by id, but the id is invalid.

Like this: 127.0.0.1:8000/api/v1/tours/ssssss - in this case, ssssss is the ID.

I'm supposed to do this by checking the name property on the object with the error: if (error.name === 'CastError'). But I don't have the name property in the error.

{
    "status": "error",
    "error": {
        "stringValue": "\"ssssss\"",
        "kind": "ObjectId",
        "value": "ssssss",
        "path": "_id",
        "reason": {},
        "statusCode": 500,
        "status": "error"
    },
    "message": "Cast to ObjectId failed for value \"ssssss\" at path \"_id\" for model \"Tour\"",
    "stack": "CastError: Cast to ObjectId failed for value \"ssssss\" at path \"_id\" for model \"Tour\"\n    at model.Query.exec (D:\\IT\\Node-Natours\\node_modules\\mongoose\\lib\\query.js:4351:21)\n    at model.Query.Query.then (D:\\IT\\Node-Natours\\node_modules\\mongoose\\lib\\query.js:4443:15)\n    at process._tickCallback (internal/process/next_tick.js:68:7)"
}

At the same time, in another case, when I create a document with an already existing name, this field appears there.

At the moment I have done a check on this field: "kind": "ObjectId". But I don't know if there will be gaps in the future because of this.
