errorECS Deployment Circuit Breaker was triggered

Question

I am trying to do the workshop https://medium.com/aws-tip/devops-zero-to-hero-7-deploying-containers-with-aws-ecs-510d1f78fb21

I already have a task execution IAM role created. I have a user with AdministratorAccess, AmazonEC2ContainerRegistryFullAccess, AmazonEC2ContainerRegistryPowerUser and SecretsManagerReadWrite policies.

the subnet launching the Fargate task is a public subnet
the inbound rules of the security group I am using with ECS Fargate allow connections from ALB

But always when I create the services, using load balancer, etc.

Show me the error:

Resource handler returned message: "Error occurred during operation 'ECS Deployment Circuit Breaker was triggered'." (RequestToken: 09d1b113-a8a6-e1e0-10fc-d97e042d2559, HandlerErrorCode: GeneralServiceException)

Hello.

Try adding 200 and 302 to the HTTP status code for the ALB's target group health check.  
The error is probably due to a redirect being performed in the WordPress container and a 302 status being returned as a response.
