I don't know what exactly is wrong, it suggests to add the yaml-language-server thingy, but I'm clueless about that. The changelog says that non populated options aren't valid anymore, I don't have those. That's all that is mentioned about image validation
What do I have to do to fix this?
Solution
Install only supports a list of strings. What you have there is a list of objects because of the use of the colon on each line
