In RabbitMQ default exchange doesn't work 'COMMAND_INVALID - invalid exchange type '''

Question

I'm learning RabbitMQ with tutorial https://www.rabbitmq.com/tutorials/tutorial-six-php.html.
I've copied code from example. But I get Exception when I run this example.

COMMAND_INVALID - invalid exchange type ''
All previous examples worked correctly.
Why did it happen? What should I do to run it?

I have RabbitMQ 3.7.16 running on my local workstation.

Here's a transcript of how I ran the code, which works fine. Some output is truncated:
