I am on an Cloud ATP database environment and have created a Rest Data Source to get vat-codes from an other Apex application ( in the same database). When I press the Test Operation button
I see the values that I expect to see.
I have created a simple classic report that uses this Rest Data Source. Creating the page is no problem ( I do not see any errors in the creation proccess) but when I run the page I get the error
ORA-20999: REST Data Source returned an HTTP error: HTTP 403: Forbidden
The api (in the other Apex application) has been created with the Authorization Required option set to No.
When I call the url directly in a browser
https://yyyyyyyy-apxdev.adb.eu-xxxxxx-1.oraclecloudapps.com/ords/cpc/vatcodes/
I see all the data. So why is my Classical report giving me this error?
