Unexpected key 'environmentFiles' : Failed to register task definition in ECS

Using aws-actions/amazon-ecs-deploy-task-definition@v1 I have added environmentFiles in my containerDefinitions of task-definition.json as:

"environmentFiles": [{
    "type": "s3",
    "value": "arn:aws:s3:::ltl-environments/.stg.env"
}],

Getting the following error:

##[error]Failed to register task definition in ECS: There were 5 validation errors:
* UnexpectedParameter: Unexpected key 'environmentFiles' found in params.containerDefinitions[0]
* UnexpectedParameter: Unexpected key 'environmentFiles' found in params.containerDefinitions[2]
* UnexpectedParameter: Unexpected key 'environmentFiles' found in params.containerDefinitions[3]
* UnexpectedParameter: Unexpected key 'environmentFiles' found in params.containerDefinitions[4]
* UnexpectedParameter: Unexpected key 'environmentFiles' found in params.containerDefinitions[5]```

@gaurav-agarwal27 the dependencies have been updated, and you should now be able to use environmentFiles. Let me know if you’re still running into issues.

It looks like it might be using an older version of the AWS SDK which does not yet support environmentFiles. Will confirm and provide more details.
