When i trying to print customer invoice getting an error:

Traceback (most recent call last):
  File "/home/ubuntu/liveAMS/openerp/addons/report/controllers/main.py", line 121, in report_download

TypeError: must be string or buffer, not None

Installed wkhtmltopdf: wkhtmltopdf 0.12.2.1 (with patched qt).

How can resolve this?

Solution

  • Odoo might be trying to load an empty PDF from the database. In this case, try these:

    1. Enable debug / developer mode - go to yoursite.com/web?debug

    2. Go to Settings > Technical > Reports > Reports

    3. Search for 'invoices'

    4. Click on the report record with name Invoices and Template Name account.report_invoice

    5. Click Edit

    6. Uncheck Reload from attachment

    7. Click Save

    Now try to print the invoice again.
