JPA Causing java.lang.NullPointerException in Spring Boot - java

I'm trying to run some unit tests in my Spring Boot application and getting the following errors:
I can't tell if this is because it can't connect to my database in Heroku (ClearDB) or if I have some annotation wrong within my code.
I have the environment variables being loaded into my application-dev.properties file at runtime, all that information can be seen at the bottom.

You are using #MockBean which, underneath, uses Mockito.mock to create a mock of your bean. The default behavior of a mock is to return default values and in this case it will return null as the default value. Hence it will break on the forEach
What you need to do is tell your mock what to do on a specific method call. In your case you might want to return an empty list. In your test method you would need to add something along these lines.
#Test
public void subscriberListNull() throws Exception {
Mockito.when(employeeService.findAll)).thenReturn(new ArrayList());
ArrayList<Subscriber> subs = aService.getSubscribers();
assertThat(subs).isEmpty();
}
This is also inline with the default for Spring Data JPA as that will never return null from a collection returning method. If there are no results you will get an empty collection.

portMapper().http(8080).mapsTo(8443) doesn't redirect http to https spring boot 2.7.4

I'm very new to Spring Boot and software development.
I want to redirect http requests to https counterpart. Https and the rest of the functionality seems to work fine
Thank you for your input!

I saw a number of questions here where answer was to add portMapper().http(8080).mapsTo(8443) to configuration. But for me this doesn't solve the issue.
I saw other much more cumbersome solutions involving TomcatEmbeddedServletContainerFactory
With lots of googling and trial and error I found this solution https://www.javadevjournal.com/spring-boot/spring-boot-ssl/
But I'm still wondering why the above solution didn't work
#Bean
public ServletWebServerFactory servletContainer() {
TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {#Override
protected void postProcessContext(Context context) {
SecurityConstraint securityConstraint = new SecurityConstraint();
securityConstraint.setUserConstraint("CONFIDENTIAL");
SecurityCollection collection = new SecurityCollection();
collection.addPattern("/*");
securityConstraint.addCollection(collection);
context.addConstraint(securityConstraint);
}
};
tomcat.addAdditionalTomcatConnectors(redirectConnector());
return tomcat;
}
private Connector redirectConnector() {
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setScheme("http");
connector.setPort(8080);
connector.setSecure(false);
connector.setRedirectPort(8443);
return connector;
}

"mvn test" 0 tests run - spring + cucumber + junit5

I have a test project where I'm trying to setup e2e api tests using rest-assured. Tests run fine if I run them from the feature files, however, when I try to run them with maven, 0 tests run. I believe there is something funky with my pom.xml but I can't figure it out...

#SelectClasspathResource("src/test/resources/example")
Typically src/test/resources is not part of the classpath.
After running mvn test have a look at target/test-classes to understand the structure of what is on the classpath.

Spring can't find Service or Repository beans to Autowire

I'm trying to run spring boot with spring data as basically as possible with swing.
However, even though all seems to be properly configured, when I try to run it, I get an error message saying it couldn't find my Service bean.
package db.westworld.dao;

}
Error message:
Parameter 0 of method setRobotService in db.westworld.view.RegisterRobot required a bean of type 'db.westworld.service.RobotService' that could not be found.
Action:
Consider defining a bean of type 'db.westworld.service.RobotService' in your configuration.
(the JDialog implementation just includes the basics)
The same also happens when I try to autowire the repository.

The parameter to new SpringApplicationBuilder() must be the class annotate with #SpringBootApplication, as shown in every Spring Boot example I've ever seen, e.g. Create an Application class in the "Getting Started - Building an Application with Spring Boot" guide.

404 on #RepositoryRestResource's url in JUnits

Something is missing or misconfigured for JUnits - I can't find.
Getting a 404 instead of 200 in Junits. The application at http://localhost:8080/app shows the expected response.

#WebMvcTest should be used only for the Controllers. Hence, #RepositoryRestResource class was not initialized.
Replacing it with #AutoConfigureMockMvc and #SpringBootTest did the trick.
Other similar Test utility annotations:
#WebMvcTest - for controllers
#JsonTest - for JSON marshaling and unmarshalling
#DataJpaTest - for repositories
#RestClientTests - for REST clients
#SpringBootTest - for everything else

Spring boot application is not running due to failure of initialization of 'requestMappingHandlerMapping'

It is a spring boot 2.0.0 application which was running earlier, but this error started after I added dependencies for spring-cloud-stream.I tried removing spring-fox dependency but it only removed the nested exception.
The complete error after removing spring-fox dependency:
ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Invocation of init method failed; nested exception is java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy

I'm just a starter in spring-cloud-stream, so any help would be appreciated.
Edit:
We found out that the mistake is in the way or place the annotation
