Building Dockerfile: Argument for @NotNull parameter 'statusText' of com/intellij/docker/DockerDeploymentStatus.newImageStatus must not be null

When I build my Dockerfile I get the a grayed out stop sign on the Services window with the tooltip Argument for @NotNull parameter 'statusText' of com/intellij/docker/DockerDeploymentStatus.newImageStatus must not be null.

I'm usign IntelliJ IDEA Ultimate 2019.3.4 and it's bundled docker plugin. 

The dockerfile builds properly as far as I can see 

Successfully built ed361e117c09
Successfully tagged django-example:latest
'django-example Dockerfile: uwsgi_app/Dockerfile' has been deployed successfully.

How can I get rid of that stop sign / forbidden / tooltip?
