For use with Laravel Vapor

[Qalaha]

When using with Laravel Vapor, I got this error: "The specified queue does not exist for this wsdl version"

Vapor support suggested: "Seems like you are trying to send to a queue named "default" and that doesn't exist. Please don't specify a queue when dispatching jobs on Vapor."

Setting
'queue' => '',
instead of
queue' => 'default',
in config->webhook-server.php solved the problem.
