export ERROR openerp.http: Exception during JSON

[Stefano7777777]

hi,

I know that I should study more, but since I managed to run almost all the import,
I would have a mistake when I export a product to prestashop.
I installed connector_prestashop_catalog_manager without error but if I export a product created in odoo in the log file appear this error and obviously the file does not appear in prestashop, is it possible to know if it depends on some connector installation error?

Hello,

This is unrelated to this project. This is a classical error in Odoo when you don't correctly configure the reverse proxy to redirect the longpolling url to the longpolling port. The only misbehavior in such case is that features using the longpolling such as the chat won't work and that logs are cluttered with this stacktrace. You should find explanations on that configuration with some research.
