This is caused by the outdated Docker version in Synology DSM. I advise urging Synology to provide an update; supporting old docker versions is a waste of time in my opinion. In the meantime, you can use the louislam/dockge:1 tag as a workaround

Thanks. So, to continue on nightly version, I added this environmental variable:

DOCKER_API_VERSION=1.41

That seems to have removed the error, but honestly, I'm not at all sure what it may have affected,

Hi, I tested the nightly version of Dockge and resolved this issues (935) without using old version /stabil version. This includes the JSON error that apear during testing and a follow-up container issue, both have been resolved.
All containers, including Uptime-Kuma and Nginx Proxy Manager, are now running correctly.
GUI setup works also correctly now.

I’d like to propose a pull request soon, but I wanted to check here first if it’s okay to proceed.

Not fully. The container now starts (good), but does not see the stacks unless I include the environmental variable DOCKER_API_VERSION=1.41.

When I look at settings (without the API version environmental variable), I see:
