Frappe Chrome PDF Error

I just installed Frappe 16 and am migrating from the headache of wkhtmltopdf to Chrome as the PDF generator. I created a custom app with a test doctype. The Chrome PDF generation itself works fine, but when I click the “PDF” button, Frappe still throws an error related to wkhtmltopdf.

I have already:

  1. Changed the default Print Settings to use Chrome

  2. Configured my custom Print Format to enforce Chrome as well

Problem: Despite these changes, the system seems to be defaulting back to wkhtmltopdf somewhere in the process.
