Model can't delete when rangeKey is createdAt

Summary:

When call Model.delete or model.delete, it happens error and can’t delete.

Code sample:

Schema

schema: {
    id: { type: String, hashKey: true },
    createdAt: {
      rangeKey: true,
    },
    schemaOptions: {
        timestamps: true,
    },
}

General

Error happens when call

Model.delete({id:'aaaa',createdAt: 1553137260667})

or

cosnt model = await Model.get({id:'aaaa',createdAt:1553137260667})
model.delete()

Current output and behavior:

TypeError: Cannot read property 'updateTimestamps' of undefined
    at Attribute.toDynamo (/node_modules/dynamoose/dist/Attribute.js:390:30)
    at NewModel.Model.delete (/node_modules/dynamoose/dist/Model.js:1007:65)
    at <anonymous>
    at process._tickDomainCallback (internal/process/next_tick.js:228:7)

Maybe, in Attribute.js

Attribute.prototype.toDynamo = async function (val, noSet, model, options) {
...
 if (isTimestamp && options.updateTimestamps === false) {
        runSet = false;
    }
    if (isExpires && options.updateExpires === true) {
        val = await this.default();
        runSet = true;
    }

this will change as below?

Attribute.prototype.toDynamo = async function (val, noSet, model, options) {
...
 if (isTimestamp && options && options.updateTimestamps === false) {
        runSet = false;
    }
    if (isExpires && options && options.updateExpires === true) {
        val = await this.default();
        runSet = true;
    }

Unfortunately that did not work for me either. Ended up doing the following:

const DDB = this.dynamoose.ddb();

AWS.config.update({
  region: DDB.config.region,
  endpoint: DDB.config.endpoint,
});

const docClient = new AWS.DynamoDB.DocumentClient();
await docClient.delete({
  TableName: this.Model.$__.table.name,
  Key: {
    <hashKey>,
    createdAt,
  },
}).promise();
