Spring boot app runs with intelliJ but crashes in docker

Question

I have a spring boot app. It is mainly a Kafka listening app and its only web application part is the health check API through the spring-boot-starter-actuator. When running locally in IntelliJ, the application runs perfectly, with no errors and no crashes. However, when trying to run the app through docker, the app starts (i can see the spring logo) and then it imidietly crashes with the next error:

[org.springframework.boot.SpringApplication] - Application run failed 
MyApp    | 2021-02-25T19:17:17.802342316Z org.springframework.context.ApplicationContextException: Unable to start web server; nested exception is org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean.

My dependency section in the build.gradle file looks as follows:

    implementation 'org.springframework.kafka:spring-kafka'

    }
    testCompile("junit:junit:4.12")
} 

My main application class looks as follows:

@SpringBootApplication()
public class MyApp {
    public static void main(String[] args) {
        SpringApplication.run(MyApp.class, args);
    }
}

Can anyone shed some light on the reason behind this issue and how to fix it? Why would it run with no problems in IntelliJ but crash with docker? Any help would be appreciated. Thank you.
