I’m using new version of ERPNext. (self hosted)
ERPNext: v11.1.28 (master)
Frappe Framework: v11.1.27 (master)
When I tried to create a quotation from lead, it is displaying an error message after I select an item.
Thanks & Regards,
This shows that’s a 404 error https://github.com/frappe/frappe/blob/develop/frappe/app.py#L164
What have you tried for example clear your caches and or reload the app.
If you manually enter the url like this what happens https://mydomain.com/desk#Form/Lead/LEAD-00729
this issue is been discussed earlier. seems like the fix is coming soon.
