Whoops\Exception\ErrorException count(): Parameter must be an array or an object that implements Countable

After updating to Freepbx 16 following the guide that I put below when trying to update the module "Call Event Logging" from version 15.0.15.14 to 16.0.5 the following error occurs:

CDR module also affected:
