There is not much information here, but the traceback mentions a ValueError. A  ValueError: Expected singleton: ir.ui.view(1244, 1247)​, indicates that a piece of code was expecting to work with a single record, but instead, it received multiple records. So make sure in you code that only one record is used.

I hope this helps!

Hi,

The error shows that there is a singleton error ie, containing more than one record . To resolve that firstly please verify that the issue is not facing from your custom addons. If it is yes, then make the necessary changes in the function. And if it is from addons. please try to upgrade the website or Website. or change the add-on files in to latest code.


Hope it helps
