AWS Simple Workflow - respondDecisionTaskCompleted Not Working? - amazon-web-services

Question

I am currently using the PHP SDK for SWF. I successfully pull decision tasks using:
$result = $client->pollForDecisionTask(array(
"domain" => "test",
"taskList" => array(
"name" => "mainTaskList"
),
"identify" => "default",
"maximumPageSize" => 50,
"reverseOrder" => true
));
$activity_type_version = "1.0";
$task_token = $result["taskToken"];
$run_id = $result["workflowExecution"]["runId"];
$last_event = $result["events"][0]["eventId"];
if($last_event == "3"){
$activity_type_name = "SlamStart";
}
I then try to register my completed decision task with the following:
$result = $client->respondDecisionTaskCompleted(array(
"taskToken" => $task_token,
"decisions" => array(
"decisionType" => "ScheduleActivityTask",
"scheduleActivityTaskDecisionAttributes" => array(
"activityType" => array(
"name" => $activity_type_name,
"version" => $activity_type_version
),
"activityId" => "1",
"control" => "something",
"scheduleToCloseTimeout" => "300",
"scheduleToStartTimeout" => "300",
"startToCloseTimeout" => "300",
"heartbeatTimeout" => "300",
"taskList" => array(
"name" => "mainTaskList"
),
"input" => "test input"
)
)
));
echo "respondDecisionTaskCompleted call went through";
The above never goes through and the last line with echo is never reached.
Why is this happening?

The decisions property has one array wrapped inside of a second array. Instead of
"decisions" => array(
"decisionType" => "ScheduleActivityTask",
"scheduleActivityTaskDecisionAttributes" => array(
"activityType" => array(
"name" => $activity_type_name,
"version" => $activity_type_version
),
"activityId" => "1",
"control" => "something",
"scheduleToCloseTimeout" => "300",
"scheduleToStartTimeout" => "300",
"startToCloseTimeout" => "300",
"heartbeatTimeout" => "300",
"taskList" => array(
"name" => "mainTaskList"
),
"input" => "test input"
)
)
Had to change it to:
"decisions" => array(
array(
"decisionType" => "ScheduleActivityTask",
"scheduleActivityTaskDecisionAttributes" => array(
"activityType" => array(
"name" => $activity_type_name,
"version" => $activity_type_version
),
"activityId" => "1",
"control" => "something",
"scheduleToCloseTimeout" => "300",
"scheduleToStartTimeout" => "300",
"startToCloseTimeout" => "300",
"heartbeatTimeout" => "300",
"taskList" => array(
"name" => "mainTaskList"
),
"input" => "test input"
)
)
)
