Quotation print to pdf, error of Page Missing or Moved

ERPNext: v11.1.39 (master)
Frappe Framework: v11.1.36 (master)

I found one error, when i print pdf, or full page, there is one error like:

Page Missing or Moved
The page you are looking for is missing. This could be because it is moved or there is a typo in the link.

i checked permission setting, all is right. and i found, only quotation module has such problem.
