I want to be able to update ecs scheduled tasks via ansible, using

- cloudwatchevent\_rule:

name: ansitest  
schedule\_expression: “cron(0 20 \* \* ? \*)”  
description: test from ansible  
targets:

- id: ansitest  
arn: arn:aws:ecs:us-east-1:111111111:cluster/ecs-cluster-test  
ecs\_parameters:  
task\_definition\_arn: arn:aws:ecs:us-east-1:11111111:task-definition/some-app:123  
task\_count: 1

am getting the following error:

ClientError: An error occurred (ValidationException) when calling the PutTargets operation: TaskDefinitionArn is empty for target ansitest

My questions -  
Firstly, is cloudwatchevent\_rule the correct command for updating ecs scheduled tasks?  
Secondly, is the format above correct?

thanks  
Derek

The below error was on 2.3.2.0  
I just upgraded to 2.4.0.0 and got the following -

`The error was: Unknown parameter in Targets[0]: "EcsParameters", must be one of: Id, Arn, Input, InputPath`

So is this maybe a bugged/broken feature?
