Assistance Needed: UI Builder Not Opening in PDI - Invalid Request Error

FarzanA07 · ‎03-20-2025

Hello ServiceNow Community,

I hope you’re all doing well! I’m currently working in my Personal Developer Instance (PDI) and encountering an issue with the UI Builder. When I try to open it, I’m seeing the following error:

*“Could not serve invalid request for UX Page Registry, sys_id: 13df404077733300cf3a2a691061bc”*

Has anyone else experienced this or have any insights on what might be causing it? I’d really appreciate any suggestions or troubleshooting steps you could share to help me resolve this. Thank you so much in advance for your time and assistance!

Best regards,

Hi @StefanMunich24

did you try to repair the UI builder plugin once?

Had the same issue when I tried to follow the UI Builder Link on the PID admin Homepage with all the Builders and Studios.

It worked for me for some reason when I started the UI Builder from All -> UI Builder
