Failed to write to Event Forwarder test config file: [Errno 13] Permission denied: '/etc/cb/integrations/event-forwarder/cb-event-forwarder.conf_test'
Service running

I can't understand as the file cb-event-forwarder.conf_test don't exist at all
Can you help me with this please ?
I already ran sudo /usr/share/cb/integrations/event-forwarder/cb-edr-fix-permissions.sh but it don't change the issue
