Error initializing clamscan: Error: connect ENOENT /var/run/clamav/clamd.ctl
at PipeConnectWrap.afterConnect [as oncomplete] (node:net:1278:16) {
  errno: -2,
  code: 'ENOENT',
  syscall: 'connect',
  address: '/var/run/clamav/clamd.ctl'
}

Check Clamv socket is existing with:

ls -l /var/run/clamav/clamd.ctl

If not, check the clamav-daemon service is running properly.

error: A hook (`session`) failed to load!
error: Could not tear down the ORM hook.  Error details: Error: Consistency violation: Attempting to tear down a datastore (`default`) which is not currently registered with this adapter.  This is usually due to a race condition in userland code (e.g. attempting to tear down the same ORM instance more than once), or it could be due to a bug in this adapter.  (If you get stumped, reach out at http://sailsjs.com/support.)
