Hi Pranavan, The current stratos-cep-extension which is based on siddhi 2.0.0 is not compatible with CEP 3.1.0 (which is based on siddhi 2.1.0), due to some API changes. You may need to apply the diff in [1 <https://issues.apache.org/jira/browse/STRATOS-866>] and build the CEP extension again, then use it with CEP 3.1.0.
The reason why we did not upgrade it because siddhi 2.1.0 does not contain the fix we need for [2 <https://issues.apache.org/jira/browse/STRATOS-1108> ].
