As already mentioned above, this error can be caused by mis-configurations so try:

• check your .env file for the proper QUEUE_CONNECTION .
• add the connection name to your work command eg php artisan queue:work database --queue=queue_name to run on database connection

In my case however, I ran into this error when using supervisor on a production server. The supervisor process failed with that error but for a newly created configuration. I had a configuration that was already running perfectly so I ended up copying the working configuration and editing it and it worked. I suspect was copying incorrectly formatted text because I pre-created the configurations locally on a text file.
