java.lang.NoSuchMethodError: org.springframework.util.Assert.noNullElements

To resolve this issue, make sure that all `spring-` dependencies have the same version number. You can use a dependency management section in your `pom.xml` to ensure that all `spring-` dependencies use the same version. For example:

```xml org.springframework spring-framework-bom 5.3.21 pom import ```

Alternatively, you can upgrade the `spring-core` dependency to 5.2.4.RELEASE as well.
