catalog-info.yaml:72

• Duplicate component definition detected. The component eds-color-palette-generator is defined twice (lines 46-57 and lines 61-72) with identical content. This will cause conflicts in the Backstage catalog. Remove one of these duplicate entries.

If the purpose of this config file is to give users access to EDS resources, then I would think that the core-react, tokens and icons is what most people are looking for. I don’t think adding the colour-generator and demo app adds any value. 🤔

I was looking for a yaml schema file to validate the contents of the file, there’s a VS Code extension that makes it easier to write catalog-info.yaml files: https://marketplace.visualstudio.com/items?itemName=vatess.backstage-catalog-helper
