Error 908 PROCESS_OUTGOING_CALL

Hello,

I am working in an application and I would like to make it able to call a phone number when clicking a green button. I use a block "ASK FOR PERMISSION" with "PROCESS_OUTGOING_CALL" authorization and a PhoneCall block with MakePhoneCallDirect but still get a message "ERROR 908 - PROCESS_OUTGOING_CALL is denied" when running the application. In fact, the phone call works but I still get this error message. How can I avoid the message and make sure that the application will work on any smartphone ?
You will find the AIA file of the application in the message.
