Missing Share Identifier: EventBridge Rule unable to trigger AWS Batch job

Question

### **Use Case**

Configured an AWS EventBridge Rule to schedule an AWS Batch Job with the provided inputs (Please refer to the the image below):
1. Job Definition ARN
2. Job Name
3. Job Queue ARN

### **Issue**

The invocation of the job fails with the exception that **shareidentifier is required** as shown in the CloudTrail logs below:

```
{
    "eventTime": "2023-08-18T23:50:14Z",
    "eventSource": "batch.amazonaws.com",
    "eventName": "SubmitJob",
    "awsRegion": "us-east-1",
    "sourceIPAddress": "events.amazonaws.com",
    "userAgent": "events.amazonaws.com",
    "errorCode": "BadRequestException",
    "requestParameters": {
        "jobName": "job-name",
        "jobQueue": "job-queue-arn",
        "jobDefinition": "job-definition-arn"
    },
    "responseElements": {
        "message": "shareIdentifier is required.",
        "__type": "ClientException"
    }
}
```

As evident from the EventBridge console, there is no way to provide a Share Identifier during rule creation.

### **Question**

How to pass a share identifier while submitting an AWS Batch job from EventBridge?

Accepted Answer

You can pass the share identifier by creating a step function and pass the aws batch job as a task  where the task specifies the following parameters as follows 
- JobName: The name of the AWS Batch job
- JobDefinition: The ARN of the AWS Batch job definition
- JobQueue: The ARN of the AWS Batch Job Queue
- ShareIdentifier: The Share Identifier

Then create the EventBridge that triggers the Step Function. For Example, Check out this EventBridge rule that triggers a stepFunction that submits an AWS Batch job with the shared  identifier passed as a parameter

{
"Name": "MyEventBridgeRule",
"EventPattern": {
"source": "batch.amazonaws.com"
},
"Targets": [
{
"Arn": "arn:aws:states:::states:startExecution",
"Id": "MyStepFunction",
"Input": {
  "Parameters" : {
"JobName": "job-name",
"JobDefinition": "job-definition-arn",
"JobQueue": "job-queue-arn",
"ShareIdentifier":"my-share-identifier"
}
}
}
]
}

Once you have created the EventBridge rule and stepFunction, you can test them by creating an batch event that matches the event pattern in the EventBridge rule
