Filter on _updatedDate - PrivateMembersData

Hi,

I’m trying to filter Members/PrivateMembersData to return all records that are updated in the last day. The query keeps returning all records. It seems like the filter isn’t working properly.

let options = {
 "suppressAuth": true,
 "suppressHooks": true
    };  
 let filterDate = new Date(
    new Date().getFullYear(),
    new Date().getMonth(),
    new Date().getDate()-1 //Yesterday
 );
 console.log(filterDate);

 wixData.query("Members/PrivateMembersData")
  .ge("_updatedDate", filterDate)
  .find(options)
  .then( (results) => {
      console.log(results);
  } );

If I modify the filter to filter on _createdDate instead of _updatedDate, the filter works.

.ge("_createdDate", filterDate)

If I change the filter to .le(“_updatedDate”, filterDate) no values are returned (data is present).
I checked the collection, _updatedDate is filled in for each record.

Am I doing something wrong, or am I missing something regarding “_updatedDate”?

Thanks,

Sam
