Dashboard to pull last JSON files uploaded to MongoDB

I am trying to build a dynamic dashboard that will display the last JSON record uploaded to a MongoDB database. I have been able to build questions that would pull the data to display, but I do not see any way to filter for the last uploaded file or a range of last uploaded files. My data has a field date_uploaded with a syntax of "2022-10-17 21:55:43.111293+00:00" and I see that I can select individual values within the table. I want to be able to dynamically select the most recently uploaded value or a range of values (i.e. the last 5 records), though.

Any thoughts or suggestions would be highly appreciated.


Hi @leonardburke3
Post "Diagnostic Info" from Admin > Troubleshooting.
Your fields in Mongo needs to be a date type like ISODate if Metabase should be able to filter with a date selector, otherwise it's basically just a string.
