Getting an error from IBM Workilght Server [This is not a function, it is an “object.”]

Using IBM Worklight Version 6.1.0.02-20160314-1430

Implemented AES on the adapter with a link to the link below. https://mobilefirstplatform.ibmcloud.com/tutorials/en/foundation/7.1/server-side-development/javascript-adapters/using-java-adapters/

It works fine, as expected in Eclipse on my local server. The generated war file and the same specified deployment for the server. From the server when I try to access the error below.

Cross-checks are listed below.

• The collected war file from the server, cross-checked for the class file and its present in it

• Server restart is performed after deployment of the war file

I can not determine where the error is.

The response from the server:
