AEM 6.3 Timewarp go is not working and giving null pointer in FakeTemplate.hasStructureSupport .

[sabhishek2400]

I just upgraded to 6.3 classic UI and for Timewarp, trying to see particular version. I am getting 500 error, As per the logs , its throwing  NPE in FakeTemplateImpl.hasStructureSupport  method, Can you help me with this.

I can see Template API has come up with hasStructureSupport method, what exactly this method is all about ?

Here is something that could possible help you find a reason for this exception.

In your system console (/system/console/slinglog) add a new logger for com.day.cq.wcm.core.impl.warp.TimeWarpResourceResolver

Set log level to trace.

Then try to use timewarp feature to switch versions.

When an error occurs check your log file for something like:

12.07.2018 15:20:06.155 *TRACE* [10.1.5.37 [1531423206099] GET /editor.html/content/xxxx/xxx/xxx.html HTTP/1.1] com.day.cq.wcm.core.impl.warp.TimeWarpResourceResolver [1531241460000] /content/xxxx/xxx/xxx => /jcr:system/jcr:versionStorage/35/cc/67/35cc6782-ffbb-447d-a350-be3c01d8ba50/1.416 @ [Tue May 15 2018 11:18:00 GMT-0400] (fake page /content/xxxx/xxx/xxx)

Use crx console to browse to that version node and check jcr:frozenNode properties.

Chances are one of the properties is invalid.

In my case cq:template was pointing to a non-existing path.

good luck

Hi dmitriyb​,

I did the same thing as you suggested, in the logs getting same fakepage for the particular page which actually exist within system.

All the properties seems to be correct, the only difference from your scenario is that my pages are scaffolding based, Does that make difference in 6.3?
