Can't create S3 batch job through boto3 - gets request invalid

I am trying to create an S3 Batch (not AWS Batch, this is S3 Batch operation) job via boto3 using S3Control, but I get an "invalid request" response. I tried it through AWS S3 batch operation through the console which worked but now I am trying to do it through boto3 to create the batch job. Attached is the code and error message.

import json
import boto3
import time
import datetime
import os
s3ControlClient = boto3.client('s3control')
def lambda_handler(event, context):
    accountId = boto3.client('sts').get_caller_identity().get('Account')
    print(accountId)
    response = s3ControlClient.create_job(
        AccountId = accountId,
        ConfirmationRequired = False,
        Operation = {

        },
