S3 Bucket Lambda Event: Unable to validate the following destination configurations

I'm trying to create an S3 bucket and immediately assign a lambda notification event to it.

Here's the node test script I wrote:

const aws = require('aws-sdk');
const uuidv4 = require('uuid/v4');

aws.config.update({
  accessKeyId: 'key',
  secretAccessKey:'secret',
  region: 'us-west-1'
});

const s3 = new aws.S3();

const params = {
  Bucket: `bucket-${uuidv4()}`,
  ACL: "private",
  CreateBucketConfiguration: {
    LocationConstraint: 'us-west-1'
  }
};

s3.createBucket(params, function (err, data) {
  if (err) {
    throw err;
  } else {
    const bucketUrl = data.Location;

    const bucketNameRegex = /bucket-[a-z0-9\-]+/;
    const bucketName = bucketNameRegex.exec(bucketUrl)[0];

    const params = {
      Bucket: bucketName,
      NotificationConfiguration: {
        LambdaFunctionConfigurations: [
          {
            Id: `lambda-upload-notification-${bucketName}`,
            LambdaFunctionArn: 'arn:aws:lambda:us-west-1:xxxxxxxxxx:function:respondS3Upload',
            Events: ['s3:ObjectCreated:CompleteMultipartUpload']
          },
        ]
      }
    };

    // Throws "Unable to validate the following destination configurations" until an event is manually added and deleted from the bucket in the AWS UI Console
    s3.putBucketNotificationConfiguration(params, function(err, data) {
      if (err) {
        console.error(err);
        console.error(this.httpResponse.body.toString());
      } else {
        console.log(data);
      }
    });
  }
});

The creation works fine but calling s3.putBucketNotificationConfiguration from the aws-sdk throws:

I've run it with a role assigned to lambda with what I think are all the policies it needs. I could be missing something. I'm using my root access keys to run this script.

I've thought it might be a timing error where S3 needs time to create the bucket before adding the event, but I've waited a while, hardcoded the bucket name, and run my script again which throws the same error.

The weird thing is that if I create the event hook in the S3 UI and immediately delete it, my script works if I hardcode that bucket name into it. It seems like creating the event in the UI adds some needed permissions but I'm not sure what that would be in the SDK or in the console UI.

Any thoughts or things to try? Thanks for your help

You are getting this message because your s3 bucket is missing permissions for invoking your lambda function.

According to AWS documentation! there are two types of permissions required:

1. Permissions for your Lambda function to invoke services
2. Permissions for Amazon S3 to invoke your Lambda function

You should create an object of type 'AWS::Lambda::Permission' and it should look similar to this:

{
  "Version": "2012-10-17",
  "Id": "default",
  "Statement": [
    {
      "Sid": "<optional>",
      "Effect": "Allow",
      "Principal": {
        "Service": "s3.amazonaws.com"
      },
      "Action": "lambda:InvokeFunction",
      "Resource": "<ArnToYourFunction>",
      "Condition": {
        "StringEquals": {
          "AWS:SourceAccount": "<YourAccountId>"
        },
        "ArnLike": {
          "AWS:SourceArn": "arn:aws:s3:::<YourBucketName>"
        }
      }
    }
  ]
}
