URL: https://github.com/apache/netbeans/issues/7275
### Apache NetBeans version
Apache NetBeans 21
### What happened
Under Services, I added a Docker Instance installed on a server which is
connected to my local network. 'Test Connection' passed. I am able to pull
images and build containers, however when I try to refresh images I receive the
following error notification and the image listing hangs on the hourglass icon
saying "Please Wait..."
java.lang.NullPointerException: Cannot invoke "java.lang.Long.longValue()"
because the return value of "org.json.simple.JSONObject.get(Object)" is null
