I made this as a 'special case'. I thought that if in the future we have more special cases we can refactor this.

[Viicos]

I'm wondering if this special case should be moved in the ObjectsApiVariableConfigurationEditor component instead 🤔, as it is purely hardcoding a json schema.

Or maybe instead of passing the array of components, only pass the relevant component to this function?

[sergei-maertens]

more accurate would also be:

type: array
items:
  type: string
  format: uri

[sergei-maertens]

I think leaving it in here is more appropriate, it fits the idea of providing the json schema for a given variable. The fact that the schema is hard coded doesn't really matter, it's the same how your fallback is a hardcoded type: string, no?
