Hi,

What could cause the Null pointer exception (mostly getting for Section rules and for other rule types as well)? and mostly these are being thrown for OOTB rules.

Version -- 7.2

Thanks.

Hello!

On reviewing the corresponding SR, it is determined that the root cause of the issue was with an OOTB rule present in the application RuleSet. This has been rectified and thus resolved.
