Step function startExecution task not returning http meta data

Question

I have a step function in which I have a task where I start execution of another step function. It usually returns the HTTP meta data (`SdkHttpMetadata` to be specific) in the output and I use the HTTP status in it to determine the Choice state I have next. But since May 4th, the output only contains `ExecutionArn` and `StartDate`, so the Choice state is failing.

```
        "StartTimer": {
            "Type": "Task",
            "Resource": "arn:aws:states:::states:startExecution",
            "Parameters": {
                "StateMachineArn": "${TimerArn}",
                "Input": {
                    "AWS_STEP_FUNCTIONS_STARTED_BY_EXECUTION_ID.$": "$$.Execution.Id"
                }
            },
            "Next": "Success?"
        },
        "Success?": {
            "Type": "Choice",
            "Choices": [
                {
                    "Variable": "$.SdkHttpMetadata.HttpStatusCode",
                    "NumericEquals": 200,
                    "Comment": " Yes",
                    "Next": "AssignTask"
                },
                {
                    "Not": {
                        "Variable": "$.SdkHttpMetadata.HttpStatusCode",
                        "NumericEquals": 200
                    },
                    "Next": "FailedToStartTimer",
                    "Comment": "No"
                }
            ]
        },
```
