Cannot change default image in Cloudbreak

[#1]

I use custom image catalog for my NiFi cluster in Cloudbreak. Cluster was built successfully and works as expected.

Now I built new custom image, updated my catalog and  should change default image for this cluster.

I know this feature was added to Cloudbreak since version 1.8, I use version 1.9.

Anyway, when I tried to change image via Cloudbreak UI, I got next response.

But if I try to use Cloudbreak default catalog, it works as expected.

So what did I miss?

In Cloudbreak documentation in step 4 I saw one NOTE - If this window does not show any images, try (?), but looks like it is not finished.

https://docs.hortonworks.com/HDPDocuments/Cloudbreak/Cloudbreak-2.8.0/manage-clusters/content/cb_upd...

Here is how my custom image catalog looks like:   

{
    "images": {
        "base-images": [

                ]
            }
        ]
    }
}

Please help me to resolve this issue.

And other question is - is it possible to change image for ambari instance?
