You may need to add the good version of aspectjrt to your dependencies based on the JDK used for building your function:
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.9.??</version>
</dependency>JDK - aspectj dependency matrix
| JDK version | aspectj version |
