Getting Blank Page or Page Defination fails to load in UI Builder

Akshay Gupta2 · ‎02-18-2024

Hi Community,

I am facing one issue in UI Builder pages. Previously it used to work fine but since Vancouver, this is a repeated issue for me. I have implemented Service Portal with UI Builder.

Issue Getting Blank Page in UI Builder Pages, have to reload again then only page contents load, and this is happening very often. I thought this could be issue with caching, But don't no ho to disable cahing for UI Builder pages.

Tried including timestamp in URL also, but still facing this issue.

If I hit same URL - 2-3 time, Page do not loads compltely and I have to reload again.

Note** No component or event is triggered - Like Page ready or Page paramer changed.

Really Appreciate the help on this.

Thanks

Akshay

Hi everyone,

Just wanted to update you all on this issue. Apparently this was a know issue with servicenow. Blank Page in UI Builder service portal. Please check sys_ux_page_registry record for portal. check if parent app is missing or not.

Cause -

ServiceNow Known Issue: The absence of the Parent App in the application configuration was identified as the root cause. The Parent App is essential for experiences created using the Portal App shell, though enforcement was lacking. Servicenow added the business rule below in order to enforce the parent app while inserting a new experience but seems it was not working.

Got the following resolution from servicenow:

Steps to Fix -

Created a new Parent App record for the portal (table - sys_ux_app).
Linked the Parent App with the portal UI theme.
Set the parent app to "UXR Base Unified App" manually
Added the Parent App back portal Application configuration (sys_ux_page_registry)

This resolved the issue for me, no longer getting blank pages on service portal developed using UI Builder.

Reference -

This is a known issue and it has already been fixed via the PRB below:
PRB1625935 - Parent App is required for experiences created using Portal App shell, but there is no enforcement.

Do give thumbsup if works for you.

Regards,

Akshay

Hi @Akshay Gupta2 ,

you can go to the UX macroponent Definitions table to edit the composition JSON for that page variant.

Navigate to sys_ux_macroponent.LIST > Look for your Page you have built > For example in my PDI i have CSM Landing page, from the composition try to remove something not required and try agian:

Hi @Community Alums

I checked composition JSON. But the thing is I am facing Blank Page issue or Main Content not loading issue in almost all the UI Builder pages. And also the size of JSON composition is very long. I have tried removing unnecessay components. But issue still exist.

Actually, I do not get Blank page every time. It is like 2 time out of 10 when I revisit same page again and agiain using URL.

Thanks
