Hi @cnfjmail
Post "Diagnostic Info" from Admin > Troubleshooting, and which database you are querying, and which type of question it is.
I'm not sure what you are doing differently, but on 0.37.3 it works:

I use MongoD native query

@cnfjmail That’s because you are not returning a date type, and using Native question, so Metabase does not know how to handle that.
