Not able to replicate through crx/de after code deployment , it is giving 500 internal server error when trying to replicate using crx/de.

Attaching screenshot for reference. 

Repro steps

• After deploying custom code on an instance, the instance restarts and a nullpointer exception occurs at "java.lang.NullPointerException: null
    at com.day.cq.replication.impl.ReplicatorImpl.getReplicationStatus(ReplicatorImpl.java:288) [com.day.cq.cq-replication:6.2.86.CQ650-B0007]" in CRXDE
• When we try to reproduce the same on a vanilla instance, the issue doesn't occur unless we do a soft restart and deploy the core bundle of our custom code again. 

Note : after every deployment instance is getting restarted and issue mainly occurs after deploying core bundle and this is happening in all the AEM environment's (local . dev , uat e.t.c)

Below are the steps tried so far to resolve the issue 

• Removed imports and exports in the core pom which could also be imported by core components
• Removed RepositoryInitializer from ui.config
• We also tried removing Environment Indicator bundle from ACS commons
• Decoupled/Removed other custom code dependencies
• Tried removing references of core components in poms

Still issue occures .

Hi @Bipsa,

I believe this is a known issue and has already been fixed in the Forms SP22 release. I would request you try upgrading your environment to SP22 and validate the use case to see if you get the same issue. 

If you still see the issue, please raise a support case via the Experience League portal to investigate the issue further.

Thanks
Pranay
