SchemaError: No list schema given for attribute when saveUnknown is true

Summary:

Getting error: SchemaError: No list schema given for attribute: sign when sign attribute has type [Object] and saveUnknown: true. Seems to work with other types like Array even if saveUnknown is enabled. I can’t use Array here though, cause this list will be populated with some objects in some cases.

Code sample:

Schema

const recSchema = new dynamoose.Schema({
  _id: {
    hashKey: true,
    required: true,
    type: String,
  },
  sign: {
    type: [Object],
  }
}, {
  saveUnknown: true,
});

Model

const Receipt = dynamoose.model('Receipt', recSchema, { update: true });

General

// Code here

Current output and behavior:

Getting the error below:

                throw new errors.SchemaError(`No list schema given for attribute: ${this.name}`);

@ElliottKoppRGA In the “docs” folder there is full documentation. Sadly other than the standard GitHub.com interface there isn’t a great way to view it currently.

If you have any ideas of how to improve it, a PR would be awesome.

@void666 This behavior has completely changed in version 2.0. I’d suggest playing around with it and leaving feedback on how it goes.
