Hi folks,

trying to solve pdf print here. I have installed latest wkhtmltopdf-0.12.2.1 but still doesn't get the result.

In one case (printing invoice) it fail with following error.  In other case pdf is generated but has 0 length.

Traceback (most recent call last):
File "/home/openerp/projects/odoo8-production/odoo/addons/report/controllers/main.py", line 121, in report_downloadresponse = self.report_routes(reportname, docids=docids, converter='pdf') 
File "/home/openerp/projects/odoo8-production/odoo/openerp/http.py", line 402, in response_wrap response = f(*args, **kw) 
File "/home/openerp/projects/odoo8-production/odoo/addons/report/controllers/main.py", line 65, in report_routes pdf = report_obj.get_pdf(cr, uid, docids, reportname, data=options_data, context=context) 
File "/home/openerp/projects/odoo8-production/odoo/openerp/api.py", line 241, in wrapper return old_api(self, *args, **kwargs)

File "/home/openerp/projects/odoo8-production/odoo/addons/report/models/report.py", line 345, in _check_attachment_use pdf = base64.decodestring(pdf) 

File "/home/openerp/python/2.7/lib/python2.7/base64.py", line 321, in decodestring return binascii.a2b_base64(s)
TypeError: must be string or buffer, not None

I think I'm missing some python module, but comparing to my other odoo server wher pdf print works I can't find the differences.

Can somebody give a hint what should I check and/or install?

Regards!

Hi Marek,

Delete the files atached to the invoice and try to print again.

It works for me.

Zbik,

your proposal to downgrade solves the "error issue" however I'm still getting empty pdf with wkhtmltopdf-0.12.1.2

I removed all wkhtmltopdf version from portage (on gentoo) and switch to custom ebuild from this guy https://github.com/sormy/gentoo-overlay as I'm using on the other server with no problems.

With wkhtmltopdf-0.12.1 from Sormy's ebuild I'm able to print pdf, but it produces the error from my first post again... :(


Empty pdf affected wkhtmltopdf version (from portage):

$ wkhtmltopdf -V
wkhtmltopdf 0.12.1.2

Working wkhtmltopdf on other server installed (from Sormy's ebuild):

$ wkhtmltopdf -V
wkhtmltopdf 0.12.1 (with patched qt)


 Any ideas?


EDIT:

Well, it seems that only 2 invoices is affected by this issue. Other documents can be printed normally. Will create a new database to see if it helps.
