Hey @SureshKumar-sterlingcheck ,

Could you please provide minimal code reproduction?

Thanks!

[SureshKumar-sterlingcheck]

const data: any = items.map((item: any) => ({
  PutRequest: {
    Item: item
  }
}))

console.debug(Array.isArray(data))

const params = {
  RequestItems: {
    [tableName]: data
  }
}
const command = new BatchWriteItemCommand(params);


const response: any = await this.dynamoDb.send(command);

this is how the console looks like for requesitem table array

{
  PutRequest: {
    Item: Content {
      id: 'temp21313',
        accountId: '000000000000',
}
  }
}
