Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Applicability

Splunk Enterprise

Description

The splunk custom apps page is not loading after upgrading to v9.0.3, which can be verified by checking in Splunk Settings> Apps>Upgrade Readiness App. 

Upgrade Readiness App



 


Investigation

image002 (1).pngWhen trying to open any custom applications, the page just shows a loading screen and never loads the application. The only app that was loaded with no issue was the Search and Reporting app. A rolling restart of the SHC was initiated and internal logs were checked, but it wasn't able to find any absolute errors pointing to the issue. It was then noticed that it was mainly happening on custom apps. All advanced .xml files were renamed and a reload was initiated. This fixed the issue; we could run the upgrade readiness app on the custom apps without any issues.

Resolution

Removing the "default" directory  
$SPLUNK_HOME/data/ui/views
let's splunk find the correct file, which had system-wide visibility (so every app can use it). The issue was resolved by removing all the flagged advanced XML and afterward, all apps loaded as expected.
