Hi,

I’m encountering an intermittent issue in my Odoo 16 instance after restoring a database. Sometimes, everything works fine, but other times, I get the following error (same db, same code)


500: Internal Server Error

Error while render the template
TypeError: object of type 'NoneType' has no len()
Template: web.login
Path: /t/t/t
Node: <t t-set="form_small" t-value="True" t-if="len(providers) > 2"/>



My Questions:
  1. Has anyone else encountered this issue, especially after restoring a database?
  2. What could cause providers to be None in this context, and how do you ensure it’s always properly initialized?
  3. Are there specific database records or configurations I should double-check after restoring to prevent this issue?

Any suggestions would be greatly appreciated! Thank you in advance!

Maybe it comes from a view.
You should look at the list of the views (yourdatabase.odoo.com/odoo/action-31?debug=1), search for the node  <t t-set="form_small" t-value="True" t-if="len(providers) > 2"/>
and check errors in this one. Or deactivate it if it's a customization?
