I create a mobile app who show local crickets score card by programming in react native expo cli. https://play.google.com/store/apps/details?id=com.rafiullahkh.lcsa Now i want to update the app and want to integrate a score card in facebook/youtube live stream. If possible then gave me some hints.

I search a lot but does not find any documentation.

I try to publish photo and video at the same post on Facebook page, using graph api.

There is error: { "error": { "message": "(#10) Application does not have permission for this action", "type": "OAuthException", "code": 10, "fbtrace_id": "Afb5tvXsF_pInAzWWIvHLoC" } }

I try to publish photo and video at the same post on Facebook page, using graph api.

I'm developing SDK for Facebook(meta) and use FBSDKGraphRequest to get some data. As the demand of access-token, I want to test the case that access-token has been invalid(mostly out of time), so I generate a short term token from fb's graph developer and wait for 2 hours until it invalid. Then I build an out-of-date token and FBSDKGraphRequest. Use FBSDKGraphRequest but nothing back(no result, no error).

I generate a short term token from fb's graph developer and wait for 2 hours until it invalid.

Use these code :

FBSDKAccessToken *access_token = [[FBSDKAccessToken alloc] initWithTokenString: @"xxxxxx"(tokenString from graph developer)                                                                        permissions:@[@"public_profile",@"email", @"user_friends"]                                                                declinedPermissions:nil                                                                 expiredPermissions:nil                                                                              appID:@"xxxxxx" (my appid)                                                                             userID:@"xxxxxx"(myuserid)                                                                     expirationDate:[NSDate dateWithTimeIntervalSince1970:1717041600]                                                                        refreshDate:[NSDate dateWithTimeIntervalSince1970:1717041500]                                                           dataAccessExpirationDate:nil];     [FBSDKAccessToken setCurrentAccessToken:access_token]; 

I generate a FBSDKAccessToken which generated by out-date tokenString and test in these code :

            FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]                                           initWithGraphPath:@"/me"                                           parameters:@{ @"fields": @"picture",}                                           HTTPMethod:@"GET"];             [request startWithCompletion:^(id<FBSDKGraphRequestConnecting>  _Nullable connection, id  _Nullable result, NSError * _Nullable error) {                 NSLog(@"request back!");                 NSLog(@"fb has error:%@", error.description);                 //get picture url             }]; 

When the token is valid(not out of date), it works and has log. But when it is invalid(out of date) , there is no log(no result no error, even no "request back!".

After long time debug and searching answer on Google, I don't find similar reason. But I find FBSDKAccessToken have a func "refreshCurrentAccessTokenWithCompletion" can also get the status of the token. So I used this to judge the token's status before FBSDKGraphRequest. But something magical happened. After I add refreshCurrentAccessTokenWithCompletion, FBSDKGraphRequest works too. It shows log "request back!".

This might be a way to solve this problem. But I think there must be a method to solve this better and some root cause.

I am running this command on my terminal :

C:\Ad-Library-API-Script-Repository-main\python> py fb_ads_library_api_cli.py -t (token) -f "id,page_id,page_name,ad_creative_bodies,spend,demographic_distribution,bylines,ad_delivery_start_time" -c "CA" -s "climate" --after-date "2024-05-01" save_to_csv file.csv 

And I get the following error :

Traceback (most recent call last): File "C:\Ad-Library-API-Script-Repository-main\python\fb_ads_library_api_cli.py", line 147, in main() File "C:\Ad-Library-API-Script-Repository-main\python\fb_ads_library_api_cli.py", line 134, in main save_to_csv( File "C:\Ad-Library-API-Script-Repository-main\python\fb_ads_library_api_operators.py", line 96, in save_to_csv with open(output_file, "w") as csvfile: ^^^^^^^^^^^^^^^^^^^^^^ PermissionError: [Errno 13] Permission denied. 

Does anyone have a solution ? i'm not sure I understand how the Permission system works in the Graph Api.

I have tried adding "encoding="utf-8" in the fb_ads_library_api_operators file to fix the encoding issue, but it didn't work (i am able to get one dataset then i get the same error all over again)

based on the <Page Public Content Access> feature and this doc https://developers.facebook.com/docs/features-reference/page-public-content-access/

I understand after Business app approval can access public page post and comments. I would like to know how to try this feature before going live or app approval ?
