Using frappe.utils.print_format.download_pdf without authentication

[ratskin]

@netchampfaris thanks for the help, but that hasn’t solved it for me.

My code:

@frappe.whitelist(allow_guest=True)
def call_download_pdf(doctype, name):
	from frappe.utils.print_format import download_pdf
	download_pdf(doctype, name)

call_download_pdf(doctype, name)

This still produces these connected errors.
Which looks similar to this other issue posted on discuss.

Now this seems to fix up. There was a syntax error with a ‘)’ missing in a .py file. Had to use python -m compileall . command

Following his advice I did this. Which turned up no errors, but my previous code still failed. I’m unsure how to resolve this and would appreciate more help.
Thank you

P.S.
I forgot to mention before, but I already tried something similar to this; I edited frappe/utils/print_format.download_pdf, line 44, to be

@frappe.whitelist(allow_guest=True)
def download_pdf(doctype, name, format=None, doc=None):

instead of:

@frappe.whitelist()
def download_pdf(doctype, name, format=None, doc=None):

allow guest doesn’t ensure that a guest will have permission to access the data;
it only allows a guest to make a call to a function.
