Hello,

I have upgraded the mautic to 5.1, but after upgrade it, one custom command is not working.  
The command is as follows  
php /var/www/vhosts/myfolder/www/bin/console vcr:cron  
but after execute it, I am getting following error  
“There are no commands defined in the “vcr” namespace.”  
I don’t get, how I can register the namespace.

Thanks
