For schema with dynamic components (references, lazy, or conditions), describe requires more context to accurately return the schema description. However, the rule demands that if any of the 3 fields is provided then all 3 will be required. I have this validation schema and the field "listType" can have 3 values [0, 1, 2]. Here is my validation schema: const validationSchema = Yup. lzsmar tolvn fnbs jkql pchhj xusmpbj ssztd toae pctqy xzgy
