Can I upload file out json to Google cloud app engine ?

[Votrung19995]

Environment:

• PHP: ver 7.2
• Framework: Laravel

I use option --write-info-json to write a json metadata file with command as blow:

LC_ALL=en_US.UTF-8 /app/storage/libs/youtube-dl -o '/app/storage/upload s/%(id)s.%(ext)s'' --no-playlist --ignore-config --write-i nfo-json --skip-download https://www.youtube.com/watch?v=LspZCNNP6aE&list=RDiE52-XXnQqs&index=4

Issue:

In my local it is working fine and stored a json file to path '/app/storage/uploads/, but when I deploy my app to google cloud app engine it is not working.

How can i out a json file to google cloud app engine ?
