Offer suggestions in dataset edit view for common mistakes #5571
Description
The error messages provided by the json schema validation are not always easy to understand. e.g. if the largestSegmentId of a segmentation layer is missing, the error is instance.dataLayers[0] does not match allOf schema "DataLayerCategories" with 1 error[s]:; instance.dataLayers[0] is not any of "DataLayerColor","DataLayerSegmentation". Maybe we can offer some suggestions below this error message
