I get the following email error message when clicking on the button which is supposed to send an invoice to a customer.

.........................File "/home/odoo/src/odoo/saas-3/openerp/addons/base/ir/ir_actions.py", line 130, in render_report return new_report.create(cr, uid, res_ids, data, context) File "/home/odoo/src/odoo/saas-3/openerp/report/report_sxw.py", line 458, in create fnct_ret = fnct(cr, uid, ids, data, report_xml, context) File "/home/odoo/src/odoo/saas-3/openerp/report/report_sxw.py", line 481, in create_source_pdf aname = eval(attach, {'object':obj, 'time':time}) File "<string>", line 1, in <module> File "/home/odoo/src/odoo/saas-3/openerp/osv/orm.py", line 505, in __getattr__ return self[name] File "/home/odoo/src/odoo/saas-3/openerp/osv/orm.py", line 435, in __getitem__ raise KeyError('Field %s not found in %s'%(name, self)) AttributeError: Got KeyError('Field name not found in browse_record(sale.order, 672)',) while trying to get attribute name on a sale.order record.

Any assistance to understand this message will be welcome.
