无法使用 API 为 Facebook 广告创建广告创意

如何解决无法使用 API 为 Facebook 广告创建广告创意

我正在使用沙盒帐户创建广告系列、广告集、广告创意和广告。我能够创建广告系列和资产。但是，当我尝试创建广告创意时，出现以下错误：

{
    "error": {
        "message": "Invalid parameter","type": "OAuthException","code": 100,"error_subcode": 1885183,"is_transient": false,"error_user_title": "Ads creative post was created by an app that is in development mode","error_user_msg": "The creative post with ads was created with the help of an app that is currently in development mode. The app needs to be in public mode to create this ad.","fbtrace_id": "AkX6eSS1E3Y5M1D5PiBmF3X"
    }
}

但是当我公开应用程序时，出现以下错误：

{
    "error": {
        "message": "Unsupported post request. Object with ID 'act_xxxxxxxxxxxxxx' 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","error_subcode": 33,"fbtrace_id": "A8zlfdjia7eCWQ3czHOYDBb"
    }
}

请帮助制作广告，然后制作广告创意。

我也无法在 Facebook 业务经理上看到沙盒帐户的广告系列和广告集。
