QWebException: "cannot concatenate 'str' and 'NoneType' objects" while evaluating
"'container '+lang_direction"
i think you are trying to concatenating a "*string*" with an "*empty value* with none type object". There is no object or value comes for a field which you specified. So you can better use that if not any value , then give "* ' '* " value. For example : ${o.number or ''}.try this
Did you setup any custom module? This error does not usually happen in core modules. Let me know if you are technical, can help you find out the root. Please here if this helps! https://github.com/odoo/odoo/issues/4974
Yes, I installed the "Report_rtl" module to enable printing reports from right to left.
I don't know how to trace odoo errors!
