I have a fargate task that I want to run as a scheduled task every n minutes. I have a task definition that works perfectly as expected (with cloud watch logs as expected and VPC connections working properly). That is when I run it as a task or a service. However, when I try to run it as scheduled task, it does not start. I checked the cloudwatch logs, however, there are no log entries in the log group. If I lookup the metrics page, I see a FailedInvocations entry under the metric name.
I understand that it is a bit tricky to schedule a task in fargate, as we have to go to cloudwatch rules, and update the scheduled task there, in order to add subnets and define a security group, as this option is not available when creating the scheduled task through my ECS cluster page.
I also have studied the documentation page here, and also checked this question. But I still cannot understand why it does not work. Thank you in advance.
