I have a Facebook Game called "Physi Bricks". The game has achievements. When the user gets an achievement, I ask if they would like to post a message with that achievement. If they click "yes" they are prompted for a message. This message is then attached to the achievement when I submit it to Facebook with my app token.
When the user doesn't choose to include a message, the Achievement is submitted successfully.
When the user chooses to include a message I get this error back from Facebook:
"Application with ID 347432048676550 has not been granted the capability to use the property message."
According to the Facebook Documentation for Creating an Achievement for a User, I can publish the "message" parameter, provided I have the "publish_actions" permission, which I do have.
How/where can I be granted the capability to use the "message" property?
