# Errors Initializing and Starting Up Policy Engine (Configuration Hints, Orca/CloudDriver/Front50)

### Issue <a href="#issue" id="issue"></a>

Policy Engine has been implemented with settings in Operator/Halyard, but it is not starting up and is causing errors in the initialization. Example may look like something below:

```

The typical cause is a non-static @Bean method with a BeanDefinitionRegistryPostProcessor return type: Consider declaring such methods as 'static'.

### Cause <a href="#cause" id="cause"></a>

Configurations on Policy Engine require a complete list of declarations. It can be easy to miss a declaration.
