How can I get Tags to be configured on the AWS Batch job started by the Eventbridge?

Question

Following [a tutorial example](https://docs.aws.amazon.com/batch/latest/userguide/batch-cwe-target.html) it is possible to configure an eventbridge rule to trigger an AWS Batch job.

It is even possible to set other container override configurations like `Environment` as a list of `Name`, `Value` objects in the request json. After using uppercase to start these attribute names, you can see them in Cloudtrail in the SubmitJob request as lowercase values that match the [job definition](https://docs.aws.amazon.com/batch/latest/APIReference/API_JobDefinition.html).

The issue I have is that we have is that the jobs started by eventbridge do not contain any tags. **How can I get Tags to be configured on the AWS Batch job started by the Eventbridge?**

Random facts:
- The submission role has `batch:TagResource` permission
- Using `Tags` or `tags` as an attribute in the transformer next to `ContainerOverrides` does not work
- Both tags have been tried with `[{"Name": "tag_name", "Value": "tag value"}]` and `{"tag_name":"tag value"}` values
- In the Cloudtrail I can see the SubmitJob coming from events.amazon.com and the request parameters include `jobName`, `containerOverrides`, `jobQueue` and `jobDefinition`
- The Batch Job Definition does have tags configured

Hello,

Below are the set of parameters that can be passed while submitting a Batch job using AWS EventBridge. Please refer this [document](https://docs.aws.amazon.com/eventbridge/latest/APIReference/API_BatchParameters.html) for more info.

1. ArrayProperties
2. JobDefinition
3. JobName
4. RetryStrategy

As you can see, it doesn't have a parameter for specifying tag information.

As per the AWS Batch [tagging resources](https://docs.aws.amazon.com/batch/latest/userguide/using-tags.html#tag-resources) documentation, the AWS Batch jobs do not support tag propagation. This means that tags do not propagate from Batch Job definition to the Batch job. They can currently be added through AWS API/CLI/SDK only.

If you prefer, you can have the EventBridge trigger a lambda function that can use AWS API/SDK to submit the Batch job by passing the tag information.

I hope this helps!
