Running Laravel 5.4 on Google App Engine

[Rick de Jong]

I proceed to run my Laravel 5.4-application on Google App Engine (GAE), with the following env_variables in my app.yaml:

APP_LOG_LEVEL: debug
APP_LOG: syslog
STORAGE_DIR: /tmp
FILESYSTEM: gae
CACHE_SERVICES_FILE: true
CACHE_CONFIG_FILE: true
CACHE_ROUTES_FILE: true
CACHE_COMPILED_VIEWS: true
BROADCAST_DRIVER: log
CACHE_DRIVER: memcached
SESSION_DRIVER: memcached
QUEUE_DRIVER: gae

I still get the error:

The bootstrap/cache directory must be present and writable.

What do I need to change to get my application working?

Thanks, 

Rick
