Hello guys! I'm trying to import 0.36 dashboard into 0.37 superset instance. Some errors are occurring when display the imported dashboard.\nI was having an Unexpected error and then I notice that in RAW mode, `granularity` is mandatory or doesn't accept null values..So, after removing the `granularity: null` from the chart parameters the error goes away. But I still having some errors with `url_param` that was working perfect on 0.36 and now I not sure is still available for 0.37 or something was changed. Any thoughts?
