Start with DockerImage.java:57, then trace the callers in ContainerRegistryDockerfileActionsProvider.java and DockerRunLineMarkerProvider.java shown in the stack trace. Investigate the null VirtualFile parent case and check existing tests around Dockerfile actions; done means the reported IntelliJ action no longer throws this exception for a root-level file.
