I was unable to find a solution after searching for several hours. Since I am quite new to this, any help would be greatly appreciated. Thank you!

You can find similar problem in this blog post.
The solution is probably as simple as adding a tomcat.version property to your Maven project’s pom.xml file
<properties>
<tomcat.version>7.0.67</tomcat.version>
</properties>
The reason is explained inside Spring Boot documentation for embedded-servlet-containers.
Spring Boot defaults to Tomcat 8, so you need to tell Spring Boot that your target is Tomcat 7.
