No more access to existing database after upgrade from CE 16.0-20250807 to CE16.0-20250819

[E4eqRL0yw0yajQJ433QL]

Since I did the mini-upgrade from CE 16.0-20250807 to CE16.0-20250819, I can no longer access existing databases. I cán access the database manager and I cán create a new (empty) database. However when accessing existing databases I get the error ERR_EMPTY_RESPONSE. Same happens when I first create a new database, then make a backup of that database through the webinterface and restore it.

The Odoo log shows an error: TypeError: get_response() takes from 1 to 2 positional arguments but 3 were given.

When I downgrade to version CE 16.0-20250807, things work as they did before.
So for now, I will remain on this version, until I understand what is going on and can take away the root-cause.

Installation:

• Synology DS723, DSM 7.2.2.72806, update 4
• Container manager (docker) version 24.0.2-1543
• Postgres version: 17.5 (running in a separate container)
• Odoo version: CE 16.0-20250807 works fine; CE16.0-20250819 shows the behavior as explained.

The same problem occurred. In addition, the invoice preview also had an error. Rolling back to 16.0-20250807 restored the problem.

After updating to release CE16.0-20250909 this issue disappeared. I have closed the issue.
