Json Validation
September 29, 2025 ยท View on GitHub
Json validation is applied to a specific filename or when it is placed in the appropriate folder. If * is present in the When is it applied, then it means that any amount of random character can be placed there. Version specific json validation is automatically applied. All elements should have received a description and title. If none are present. Then that version hasn't been supported yet. You can request one as an issue. If a json validation is missing, then post an issue. And one will be made in the future unless a good reason why not has been given.
