Describe the feature

The ability to provide the task definition ARN as a JSONata/JSONPath in aws_stepfunctions_tasks.EcsRunTask with the .sync integration pattern.

Use Case

Our team has a requirement to run a ECS RunTask sfn task with the .sync integration pattern by using an ECS task definition generated by a subsequent ECS RegisterTaskDefinition sfn task. The most practical way to reference the newly created task definition ARN in the RunTask sfn task is via a JSONata/JSONPath expression. Currently the aws_stepfunctions_tasks.EcsRunTask only accepts a aws_ecs.TaskDefinition. The aws_stepfunctions_tasks.CallAwsService cannot be used a work around since it does not allow the integrationPattern to be set to aws_stepfunctions.IntegrationPattern.RUN_JOB.

Proposed Solution

This feature may be introduced as a new string attribute within aws_stepfunctions_tasks.EcsRunTaskProps, taskDefinitionArn, where either the task definition ARN or a JSONata/JSONPath which evaluates to the task definition ARN may be provided. CDK users must then provide either a taskDefinition or taskDefinitionArn but not both.
