Webkit Reporting Error: Coercing to Unicode

Whenever i try to print a report from the webikt (e.g. General Ledger), i get the following error message:

coercing to Unicode: need string or buffer, bool found (<type 'exceptions.typeerror'="">, TypeError('coercing to Unicode: need string or buffer, bool found',), <traceback object="" at="" 0x0326edf0="">)

I set the webkit_path system parameter to 'E:\ERP\webkit\wkhtmltopdf\wkhtmltopdf.exe' (without the quote marks).

Installation: OpenErp V7 (Dutch) Windows Vista 64bit

I am not a sysadmin or programmer, and I have no idea what to try next.


The error means that a certain field that was required on the report was not supplied. For example, when you print out an invoice and it wants to display the partner address, but no address was given. In this case, it could be any of the information on your report.

Dear try this first:


if it did not fix the issue and gaive you a new error try to perform an update of openerp. It appears that your account_financial_report_webkit module is newer than the report_webkit module bundled with openerp. The change in the report_webkit module was introduced in June 2014.
