Hi,

This error is showing on my logs, I didn’t caught the cause so I’m wondering if anyone have an idea of what problem could be?

Tryton server and the client app running without inconveniences

The user cookie is some new feature that just landed to development version.

If you are using the development version you should update your database. Otherwise you should install the version from the proper series.

Actually I am using the branch origin/5.8 for trytond, but for the client desktop app I already notice now that I’m on default.

The version that appear on client is 5.8.2. With 5.8.1 if fine to use with 5.8 server?

You should always use the same series/branch to have compatible versions. Otherwise you may found errrors like the one you are posting because the client is incompatible with the server.

Yes, they are both compatible because they have the same two first digits (what we call series)

The last digit is used for newer bug fixing versions and they will never contain an incompatible change.
That’s our policy.
