Why are Some jenkins dashboards not loading for web UI en-GB locale

[VimalKris]

I'm using splunk:8.1-debian image from dockerhub to create Splunk Enterprise application. Once the container is running, I installed Splunk App for Jenkins using the 'install app from file' option from Splunk UI.

Upon navigating to some dashboards (eg health), the dashboards are not loaded and browser console has javascript error.  Splunk automatically detects the browser's default language and return en-GB for locale.

When I explicitly change web UI locale from en-GB to en-US, all the dashboards are loaded properly.

Dear VimalKris,

have you been able to resolve this issue?

If so, it would be very nice if you could provide me with some directions on how to do it.

Thank you.
