Remote execution error: RuntimeError - Could not use any proxy

Problem:
Hello. I am trying to configure remote_execution plugin and all the time I receiving the next error:
Failed to initialize: RuntimeError - Could not use any proxy. Consider configuring remote_execution_global_proxy, remote_execution_fallback_proxy in settings
I have only one smart_proxy installed on foreman localhost, with dynflow in on it. SSH key has been created automatically and uploaded to the test host. Network has been created and smart proxy attached to it.

Expected outcome:
I’d like to have remote execution working

Foreman and Proxy versions:
remote_execution 1.8.2
smart-proxy1.22

Foreman and Proxy plugin versions:
