Can you try to rebuild the clientlibs?


Also, do you see any error in the error.log ?

Please rebuild the clientlib as suggested here. This should not be happening.

I tried Rebuilding clientlibs, but no luck, when looked into logs  it gave this.

This looks like an upgrade bug - this will not happen on a fresh instance of AEM. Please open a support ticket,

smacdonald2008​ Sure raising it. Thank you for the support.

Looking at the error, Setting up a DEBUG logger on the following classes will provide more info:

  • org.apache.jackrabbit.oak.plugins.index
  • org.apache.jackrabbit.oak.query

Hello Kamal,

Customizations under apps might be causing this issue. If you have any overlays, try to move them to tmp directory and recompile.

Also, check if you have modified the config -> com.day.cq.search.impl.builder.QueryBuilderImpl.config.

Hello Vish.dhaliwal​,

Yeah we where overlaying few files, one of the environment it caused the issue, so we moved and recompiled it, it worked.

Thank you for the reply.


Level 1

Hello @Vish_dhaliwal,


What should be done if we have changed something here ->  com.day.cq.search.impl.builder.QueryBuilderImpl.config.


Querybuilder search throwing NPE and assets console is also not loading. The config above mentioned is set to older values npw, but still no luck. If at all the config is changed and reverterted back, is ther any other way to get these console back working?


Thanks in advance,

Hello Saroja,


The issue you are facing might not be because of the changes you did in the config com.day.cq.search.impl.builder.QueryBuilderImpl.config. 

You would need to investigate it. Can you provide the exact error message? Do you also have overlays for any of these consoles?
