Exception in retrieving Historical data for option

PFA screenshots.

Java code and Exception stack.

Is the problem in the code?

Is the problem in the Java API of Kite?

Today evening I paid for Historical data access.

@sujith @rakeshr or Rainmatter or Zerodha team member-
If the error is in my code, let me know.
If not, please note ... I am paying for Java API, please show Java documents, unlike my previous queries where non-Java related bulk set of likes were sent.

If any other forum member has experienced similar issue, please answer solution.
