Cannot Add People to Custom Audience

Question

I can successfully create a blank custom audience, but when I try to add people I am unsuccessful. It is weird because I get success messages back from facebook, but when I go to power editor to view, the audience says "No File Uploaded". Even after waiting for hours, nothing happens.

I have tried using both the current migration and the October first migration, and for the current migration I receive "true" and for the October first migration I receive an audience_details object that has num_received=9000 (the number of audience members). Has anyone experienced similar problems? Below is my code and the JSON I'm sending to fb.

public Boolean addPeopleToAudience(String customAudienceId, JSONObject payloadJsonObject) throws FSSocialAuthException, JSONException {
    //october 1st migration (with return type CustomAudience class)
    //return getSessionClient().publish("/"+customAudienceId+"/users", CustomAudience.class, Parameter.with("payload", payloadJsonObject.toString()));

    //current migration (with return type Boolean)
    return getSessionClient().publish("/"+customAudienceId+"/", Boolean.class, Parameter.with("users", payloadJsonObject.get("users").toString()), Parameter.with("hash_type", "sha256"));
}

JsonObject being sent to FB:

{"users":"[{\"email_hash\":\"f1904cf1a9d73a55fa5de0ac8279\"},{\"email_hash\":\"f1904cf1a9d73a55fa50bdcd0866552bb79\"}...]}

The json is converted to a string before the call, and I get "true" response from facebook. I have tried using a "/"+customAudienceId+"/users" endpoint for the current migration, but I receive an oAuth error.

Thank you for any insight/experiences you have to share!!!

Answer 1

In app settings migration, the new migration wasn't switched on. It works after using new migration and toggling that on.
