I get this error when the flow runs. I have not changed anything from my setup

```Submission failed. botocore.exceptions.ClientError: An error occurred (UnrecognizedClientException) when calling the RegisterTaskDefinition operation: The security token included in the request is invalid```

Hi Luca,

At a glance, this looks like a permissioning error. Validate the keys you're using are still valid and being injected properly
