'Unable to access CDI

I have a class that contains a method annotated with @PostConstruct which fetchs list of customers

    @ViewScoped
    @Named
 public class CustomerController extends AlertResponse {
  @PostConstruct
    public List<Customer> init() {
    ResponseEntity<List<Customer>> listResponse =
            restTemplate.exchange("http://localhost:8030/api/customers/listCustomers",
                    HttpMethod.GET, null, new ParameterizedTypeReference<>() {
                    });
    customersList = listResponse.getBody();
    return customersList;
}

When i run the application i get this error

When i removed these lines, the view is rendred fine

           <p:column headerText="Customer Status" sortBy="#{customer.customerStatus}"
                          filterBy="#{customer.customerStatus}">
                    <ui:repeat value="#{customer}" var="data">
                                                <h:outputText rendered="#{data.customerStatus == 'Unlocked'}">
                                                    <p:tag styleClass="p-mr-2" severity="success" value="UnLocked"
                                                           rounded="true"/>
                                                </h:outputText>
                                                <h:outputText rendered="#{data.customerStatus == 'Locked'}">
                                                    <p:tag styleClass="p-mr-2" severity="danger" value="Locked"
                                                           rounded="true"/>

                                                </h:outputText>
                                            </ui:repeat>
                </p:column>

@PostConstruct is for initialization purposes like opening a database connection. Methods annotated with @PostConstruct must have void return type and no parameter:

void init() { ...
