Confluence Notification box stays empty

[Fabian_Ebner]

Hello everyone, 

For some users (all except admin) the Notification Box stays empty. 

When I try to view the notifications with an non-administrative user the box stays blank and nothing happens. 

However in the log I can find some Stacktraces. 

The Log-Analysator suggested trying this: https://confluence.atlassian.com/confkb/confluence-quicknav-gadget-displays-gadget-quicknav-search-as-default-search-value-794372434.html?utm_medium=logScan&utm_source=STP

I also emptied the plugin-cache according to https://confluence.atlassian.com/confkb/how-to-clear-confluence-plugins-cache-297664846.html

But that did not solve my problem. 

However the Log displays the following error:

2018-08-23 14:02:54,621 ERROR [http-nio-8090-exec-1] [mywork.host.rest.ExceptionLogger] toResponse Exception thrown from REST resource
-- referer: https://<confluence-url>/plugins/servlet/notifications-miniview | url: /rest/mywork/latest/notification/nested | traceId: 36f4935864f2af1e | userName: dsb
java.lang.NullPointerException: null value in entry: page=null

My general setup:

Confluence runs in Version 6.1.2 with an Postgres-Database. SSL is terminated by an Apache-Proxy on Port 443. The certificate of the Root-CA is in the Trust-Store of the Confluence-JRE.

I hope you can help me. 

Kind regards 

Fabian

Hello Fabian, thank you for sharing this with our Community!
It seems that your instance is affected by the problem described here:

Workbox notifications throws 500 response error

Basically, there might be a problem with the application links between Confluence and other applications. You will need to check them and also the oauth tokens within the other applications so the authentication with the other app is working correctly.

Let us know if this helps you out!

Hi Diego,

Thank you for your suggestion, but I havent't configured any Application Links... Do you have any other suggestions?

Kind Regards

Fabian
