I am trying to deploy Retool to ECS Fargate, but the CF stack will not complete. Each of the "CreateService" steps fails with an AccessDeniedException.
Resource handler returned message: "Invalid request provided: CreateService error: Access denied (Service: AmazonECS; Status Code: 400; Error Code: AccessDeniedException; Request ID: ; Proxy: null)" (RequestToken: , HandlerErrorCode: InvalidRequest)
The stack has been assigned an IAM role which provides full access to ECS APIs from CloudFormation, but the stack creation consistently fails at this point.
Any suggestions?
