New table attributes are hidden from API

Hi,

For several days ago, I created new attributes to one of our tables in ACS. The modifications were published without errors and I can see the attributes in place in ACS.

However, when I make a GET request from Postman, I do not see the new attributes in the table, and when we make a POST request and assign a value to one of the new attributes we get error message from Postman: "MyAttribute" is not valid for the 'cusMyTable' resource.

Why is that happening? We need to make POST requests from AEM to ACS, but that is not working right now because the new attributes are not showing up on the API side.

I appreciate your help!
