I follow this instruction to create a test Facebook page:
https://developers.facebook.com/docs/apps/test-pages/
But by 3. step (post /user_id/accounts to create the test page) I got following error:
{ "error": { "message": "Unsupported post request. Object with ID 'xxxxx' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api", "type": "GraphMethodException", "code": 100, "error_subcode": 33, "fbtrace_id": "ARSn-O9fymI7GjnBlXJpi9T " } }
according to the 2. step, I have added pages_manage_metadata and pages_read_engagement access right to the test user. What is still missing here ? can you help ? thanks.
