Getting 'Internal server error' while clicking on Administration tab in editor view in backoffice.

[Former Member]

We are getting an 'Internal server error' while clicking on 'Administration' tab in editor view in backoffice, hybris 6.1 . This error is occurring intermittently for various entities in backoffice in different environments. Could you please provide a direction to debug this further.

PFB the error :

 java.lang.NullPointerException: while trying to invoke the method de.hybris.platform.core.model.user.UserModel.getDisplayName() of a null object returned from de.hybris.platform.hmc.model.SavedValuesModel.getUser() at de.hybris.platform.platformbackoffice.labelproviders.SavedValuesLabelProvider.getLabel(SavedValuesLabelProvider.java:42) ~[?:?] at de.hybris.platform.platformbackoffice.labelproviders.SavedValuesLabelProvider.getLabel(SavedValuesLabelProvider.java:1) ~[?:?] at com.hybris.cockpitng.labels.impl.DefaultLabelService.getObjectLabel(DefaultLabelService.java:85) ~[cockpitcore-2.5.4-RC1.jar:?]

Hello Aswathy,

SavedValuesLabelProvider was indeed prone to NullPointerException and the fix will be included in 6.6.

For the quick fix I would extend the SavedValuesLabelProvider, override the #getLabel(final SavedValuesModel savedValues) and register it as a bean instead default provider. In this method you can add the nullcheck:

 final UserModel user = savedValues.getUser();
 final String changedByValue = user != null ? user.getDisplayName() : null; 

I will figure out if there are plans for backporting this issue and get back to you.

Best regards, Michał

We might backport it in the future but we can't promise that we will patch it during 6.6 development.

Hello , Thanks for the reply. But I am unable to find this file 'SavedValuesLabelProvider' in any of the extensions (including platformbackoffice/platform) in hybris6.1 ,hence I am not able to implement the above mentioned fix . Could you please help me?

there might be a problem in how classpaths are defined in the project. Could you manually add a platformbackoffice_bof.jar located in hybris/bin/ext-platform-backoffice/platformbackoffice/resources/backoffice to your project? This class is located there.

Thanks , I did the same suggested and was able to get the expected results . But to deploy in production it would be difficult to add platformbackoffice_bof.jar in class path . Hence i was looking at option to write an independent labelprovider for the purpose,but i am not sure of the logic in the remaining methods. Could you please share the 'SavedValuesLabelProvider' java file so that i can implement the same.

, On checking further i can see a number of entries in SavedValues table with null user field. Would that be the root cause of the issue . Could you suggest if any issue in the save logic.
