Warning with odt template

Guys, after updating to V18.0.2, when I’m generating commercial proposals using odt plugs, these errors appear in the page header.

Warning : Invalid argument supplied for foreach() in /home2/lanix103/public_html/crm/includes/odtphp/odf.php on line 271

Does anyone have an idea what this is about?

have you reported this as an issue on github?

Thank you for the warning. I am interested in following this up before upgrading to 18.02

I just reported it, thanks for the tip.
