Has something changed in the Wix API or database recently?

Has something changed in the Wix API recently? My integration which uses the backend API via http-functions.js and calls wixData. query ( “Members/PrivateMembersData”) and wixData. query ( “Members/Badges” ) has suddenly stopped working in the last few days.

I will investigate further, but I just wonder whether there’s been a change to the API or the database structure that would cause backward compatibility issues?

I’ve now found the problem. It seems that the “contactId” property of the member object has been renamed “_id”.
