Odoo Community Edition version 14 / Wkhtmltopdf version 0.12.6 (with patched qt)
When printing a report with a large number of records (for example, printing standard Sale Order report with more than 300 records), the system displays this error after waiting for a while.
Wkhtmltopdf failed (error code: -9). Message: b"
This error happens in every report when the number of records is high enough.
I have searched in Google and the official Github issue. There are no solutions to this problem.
I have already set client_max_body_size to 25M in nginx, but the problem still persists.
I would like to solve this error and successfully print reports with large number of records.
Any suggestion is welcome.
