[7.0] Export quantity of product failed

Hello,

When we click on button "Update all the products stock quantities",
the next error occurs :

Traceback (most recent call last):
  File "/home/rdeheele/openerp_buildout/parts/connector/connector/queue/worker.py", line 122, in run_job
    job.perform(session)
  File "/home/rdeheele/openerp_buildout/parts/connector/connector/queue/job.py", line 460, in perform
    self.result = self.func(session, *self.args, **self.kwargs)
  File "/home/rdeheele/openerp_buildout/parts/prestashoperpconnect/prestashoperpconnect/product.py", line 481, in export_inventory
    return inventory_exporter.run(record_id, fields)
  File "/home/rdeheele/openerp_buildout/parts/prestashoperpconnect/prestashoperpconnect/product.py", line 453, in run
