I think it failed because of the new build of the microservice, the service was unable to run with the following error :

" java.lang.UnsupportedClassVersionError: com/glencoesoftware/omero/ms/image/region/OmeroVertxLauncher has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

The build is Java 11, Java 8 is used. We should align to Java 11 since the microservice is by default only tested using Java 11+

Yes, it is necessary to install Java 11 for molecule testing. In addition, there is an error on sha256 for the build.
I have created a branch based on this PR (https://github.com/khaledk2/ansible-role-omero-ms-image-region/tree/fix) and applied that and it has passed on:
https://github.com/khaledk2/ansible-role-omero-ms-image-region/actions/runs/9964537072

sha256 I forgot to update it after tagging see https://github.com/ome/omero-ms-image-region/releases/download/2024.07.16/SHASUMS
Since your build used Java 8, we now need to check the version on idr-testing

I have modified my local branch https://github.com/khaledk2/ansible-role-omero-ms-image-region/tree/fix and added all the supported Java versions.
I have used the new build on:
https://github.com/jburel/omero-ms-image-region/releases/tag/2024.07.17 from ome/omero-ms-image-region#5
I have added a new attribute java_version whose default value is 11.
test has passed on:
https://github.com/khaledk2/ansible-role-omero-ms-image-region/actions/runs/9996241247

A new microservice build is available so I have created a new branch (new_ms_release) based on this branch. It also contains a fix for re-install issues using a new MS build.
