Fabric8 Docker Maven Plugin: docker:tag fails with Cannot invoke "BuildImageConfiguration.cleanupMode()" because "buildConfig" is null

Question

I use FabricIO's Docker Maven Plugin.

I'm trying to create a docker tagged image with Docker Maven Pugin.

The build goal works, but when trying to tag the image, DMP fails:

Execution start of goal io.fabric8:docker-maven-plugin:0.40.2:tag failed: Cannot invoke "io.fabric8.maven.docker.config.BuildImageConfiguration.cleanupMode()" because "buildConfig" is null

docker-maven-plugin version : 0.40.2 (latest 2022-09)
Maven version (mvn -v) :

• Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)
• Java version: 18.0.2-ea, vendor: Private Build, runtime: /usr/lib/jvm/java-18-openjdk-amd64
• Ubuntu 22.04

I've also opened a bug here since it does not behave according to the documentation:e https://github.com/fabric8io/docker-maven-plugin/issues/1610

But maybe - Is there something could be doing wrong?

Here is the plugin part of my pom.xml.
Note that I put the docker:tag goal in place of docker:start so that it runs after docker:build if that being missing was the cause.
