## CannotInspectContainerError
<a name="cannot-inspect-container-1"></a>

This error occurs when the container agent can't describe the container through the container runtime.

When using platform version `1.3` or earlier, the Amazon ECS agent returns the reason from Docker.

When using platform version `1.4.0` or later (Linux) or `1.0.0` or later (Windows), the Fargate agent returns the reason from `containerd`.
