When I tried to submit an API from browser to trigger the backend job, I got an error message in tomcat log and application log. the org.apache.tomcat.util.codec.binary.Base64 was imported in the code and I am sure there is a method Base64.encodeBase64() in the verison tomcat-embed-core-9.0.60.jar which is included in maven dependencies. Any one has any sugguestion how to debug? tomcat-server: 9.0.89
