Getting null pointer exception in Promotion engine in DefaultRuleEngineKieModuleSwapper

Hi All,

We are getting the below exception stack trace in our prod environment:

ERROR [RuleEngine-module-swapping-0] -[J= U= C=] (cos) [DefaultRuleEngineKieModuleSwapper] Exception caught: {} java.lang.NullPointerException: null at de.hybris.platform.ruleengineservices.maintenance.tasks.impl.ProvideModifiedRuleCodesPostTask.execute(ProvideModifiedRuleCodesPostTask.java:44) ~[ruleengineservicesserver.jar:?] at de.hybris.platform.ruleengine.init.tasks.impl.DefaultPostRulesModuleSwappingTasksProvider.lambda$1(DefaultPostRulesModuleSwappingTasksProvider.java:35) ~[ruleengineserver.jar:?] at de.hybris.platform.ruleengine.init.impl.DefaultRuleEngineKieModuleSwapper.lambda$0(DefaultRuleEngineKieModuleSwapper.java:155) ~[ruleengineserver.jar:?] at java.lang.Iterable.forEach(Iterable.java:75) ~[?:1.8.0_221] at de.hybris.platform.ruleengine.init.impl.DefaultRuleEngineKieModuleSwapper.switchKieModule(DefaultRuleEngineKieModuleSwapper.java:155) ~[ruleengineserver.jar:?] at de.hybris.platform.ruleengine.init.impl.DefaultRuleEngineKieModuleSwapper.lambda$23(DefaultRuleEngineKieModuleSwapper.java:908) ~[ruleengineserver.jar:?] at de.hybris.platform.core.AbstractTenant$5.run(AbstractTenant.java:2460) [coreserver.jar:?] at de.hybris.platform.core.TenantAwareThreadFactory$1.internalRun(TenantAwareThreadFactory.java:159) [coreserver.jar:?] at de.hybris.platform.core.threadregistry.RegistrableThread.run(RegistrableThread.java:134) [coreserver.jar:?] ERROR [RuleEngine-module-swapping-0] -[J= U= C=] (cos) [DefaultPlatformRuleEngineService] Kie Containers initialisation/swapping failed: RulesModule:promotions-modulenull line 0 : null

Can anyone guide me here what this is about? Is this error related to publishing of promotion or while calculation?

Thanks!
