[Step Functions] Run ECS Task with dynamic Task Definition

❓ Run ECS Task in Step Functions with dynamic Task Definition

The Question

I'm wondering why this can't be an ITaskDefinition, since I'd like to dynamically pull the task definition from the input. According to the Step Functions UI it's possible to do so

aws-cdk/packages/@aws-cdk/aws-stepfunctions-tasks/lib/run-ecs-task-base.ts

Lines 18 to 24 in 0f0e205

	/**
	* Task Definition used for running tasks in the service.
	*
	* Note: this must be TaskDefinition, and not ITaskDefinition,
	* as it requires properties that are not known for imported task definitions
	*/
	readonly taskDefinition: ecs.TaskDefinition;

Environment

• CDK CLI Version: 1.21.1 (build 842cc5f)
• Module Version: @aws-cdk/aws-stepfunctions-tasks": "1.19.0
• OS: OSX Catalina
• Language: TypeScript

Hello @skorfmann -

I've re-classified this as a feature request.

Can you explain how changing this to ITaskDefinition would enable to you to pull the task definition from the input?

Thanks.
