meta ad library PermissionError: [Errno 13] Permission denied

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)
