Attempting to set the ECS task timeout through the Jenkins web interface fails.
This appears to be due to the typo correction for slaveTimoutInSeconds not being performed in https://github.com/jenkinsci/amazon-ecs-plugin/blob/master/src/main/resources/com/cloudbees/jenkins/plugins/amazonecs/ECSCloud/config.jelly
As a result, it's still trying to set slaveTimoutInSeconds instead of slaveTimeoutInSeconds. Similarly, it doesn't display the current value due to the same issue.
This is using version 1.19 of the plugin.
