Docker Compatibility (Ubuntu 24.04 Upgrade)

[GreenGrassBlueOcean]

Docker Version Instability: The default Docker installation worked fine initially. However, after running an OS update (apt-get upgrade), Docker updated to version 29.1.3. Immediately after this upgrade, ShinyProxy began failing with ValueInstantiationException (Null author). Resetting the VM to a fresh state (default Docker version) resolved this, confirming the incompatibility lies with the newer Docker version's metadata format.

Also noticing the same after a Docker upgrade:

Caused by: jakarta.ws.rs.client.ResponseProcessingException: com.fasterxml.jackson.databind.exc.ValueInstantiationException: Cannot construct instance of org.mandas.docker.client.messages.ImmutableImageInfo$Builder, problem: Cannot build ImageInfo, some of required attributes are not set [parent, dockerVersion, author]

Hi

Can you try using version 3.2.2 of ShinyProxy? This version was released to fix the incompatibilities with the new Docker version.

If you are using Docker Swarm, you can use a snapshot version, see #578

i am using the droplet version of shinyproxy https://marketplace.digitalocean.com/apps/shinyproxy which still uses 3.2.0.
Please advice how to upgrade this safely as more users might use this.
