As of this afternoon, our REST API fails when including localhost in the JSON body?
As of this afternoon/morning any REST POST calls to our Mendix apps in the Mendix Free Sandbox are failing if they include “localhost” in the JSON body of the request. We get a 403 Forbidden error. Anyone else experiencing this too? EDIT: It seems to happen in any type of API request, REST / POST / PUT, as long as the request body contains the words ‘localhost’ the request fails with a 403 error. EDIT 2: I just got a reply from support that something has indeed changed in the Free Tier v4 cloud that blocks this. There will be release notes about it soon with more information. But it looks like we’re going to have to adjust the way our API works.
