Hi Hemika, Can it be you are facing an issue related to the bug in [1]?
There is a bug at event builder side currently when there are no message properties. The workaround is to specify at least one message property at the custom input adaptor level. Can you set a dummy message property in the custom input event adaptor and see if this is resolved? If this is the issue, maybe we can patch it for CEP 3.1.0.
