Getting Internal Server Error in SAP Hybris Backoffice

[former_member1266774]

Hi,

We've recently upgraded to CX 1905.18 from 1905.7 after which we are facing issue with Backoffice wherein we get an error popup saying "Internal Server Error" as in the screenshot attached when something is being loaded.

Additional Info: We're facing this issue even while logging out of the backoffice.

We're getting following error in the console.

Any pointers will be really appreciated. Thank you.

I have the same problem on my machine. Strangely enough none of my project teammates have it.

Anyway I discovered that 19.05.18 still uses zk-8.6.02.jar but they have patched the ClientInfoEvent class in cockpitframework-19.05.18-RC1.jar and added the getZoneId() method there.

So it seems that for some reason the classloader uses the original ClientInfoEvent.class on some machines and on others the patched one. Unfortunately I don't have a clue how tell the classloader which class to use.

Issue was introduced with 1905.18. In 1905.17 it's okay.

Probably wrong version of zk framework. getZoneId exists not before 9.0.0
