See if ConfluentRegistryAvroDeserializationSchema class works better

Here is my pom.xml mixed with my dependencies from the other pom.xml. What am I doing wrong?
...ANSWER
Answered 2020-Aug-27 at 06:54The error appears when flink-clients is not in the classpath. Can you double-check if your profile is working as expected by inspecting the actual classpath?
