file_put_contents(): failed to open stream: No such file or directory on POST /oauth/token

[wwwroth]

• Laravel Version: 6.2.^
• PHP Version: 7.3
• Database Driver & Version: MySQL 8

Description:

Occasionally I receive random file_put_contents error from the Filesystem facade when retrieving an oauth token. It seems to resolve itself so I think maybe it's a locking/filesystem issue? We're running this application on Azure's app service using their default Linux container. Stacktrace and console log below.

Try to do php artisan optimize if not work check permission on root directory
Try to do that in laravel root directory using root user
chmod -R 775 ./*
chown -R www-data ./*

All the permissions are correct and this error only happens occasionally, what seems like random.
