Spring boot application with swagger 2 gets null on run()

Question

I have a simple Spring Boot application for an API what I wanted to document with Swagger. I am getting a NullPointerException in the main class.

My Main Class:

    package com.local.parking.test;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.web.bind.annotation.CrossOrigin;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    @SpringBootApplication
    @CrossOrigin(origins = "http://localhost:4200", allowedHeaders = "*", methods = { RequestMethod.GET, RequestMethod.POST, RequestMethod.PUT, RequestMethod.DELETE }, allowCredentials = "true")
    //@ComponentScan(basePackages = {"com.local.parking.test.config"})
    public class ParkingApplication {
    
        public static void main(String[] args) {
            System.out.println("Parking");
            SpringApplication.run(ParkingApplication.class, args);
        }
    
    }

The error was thrown here:

SpringApplication.run(ParkingApplication.class, args);`

Stack Trace:

My Swagger config class:

            return new Docket(DocumentationType.SWAGGER_2)
                    .select()
    //                .apis(RequestHandlerSelectors.basePackage("com.example.controller")) // Set your base package here
                    .apis(RequestHandlerSelectors.basePackage("com.local.parking.test.parking"))
                    .paths(PathSelectors.any())
                    .build()
                    .apiInfo(apiInfo());
        }
    
        private ApiInfo apiInfo() {
            return new ApiInfoBuilder()
                    .title("Parking Management API")

        }
    }

What causes the null pointer or how can I fix it?
