Quick question I setup an event source mapping from msk to Lambda (the lambda and msk are both in my VPC which was created using crosswalk with 2 public subnets and 1 private subnet

export const vpc = new awsx.ec2.Vpc('vpc', {
    subnets: [
        { type: 'public' },
        { type: 'public', name: 'test-3' },
        { type: 'private' },
    ],
    numberOfNatGateways: 2
})

But when I check the status of my ESM I see this message under

LastProcessingResult

"PROBLEM: Connection error. Please check your event source connection configuration." After doing some digging and finding articles like https://awsfeed.com/whats-new/compute/using-amazon-msk-as-an-event-source-for-aws-lambda I'm at a loss for what the issue is FYI: ingress/egress are both allowing all traffic for the SG, and for the VPC config for both the consumer lambda and the msk cluster I'm using the first 2 subnets

vpcConfig: {
      securityGroupIds: [securityGroup.id],
      subnetIds: PRIVATE_SUBNETS
    }
