Error on loading dashboard in Tryton 6.0


At first I want to thank all for this new release.

I updated without problems, processed additional steps in PostgreSQL, described in ‘Migration from 5.8 to 6.0’. It seem that all was OK, except Dashboard. When I try load it from menu, I get the next error:

Traceback (most recent call last):
  File "/trytond/", line 117, in dispatch_request
    return endpoint(request, **request.view_args)

  File "/trytond/", line 187, in get
    return self._pool[self.database_name][type][name]
KeyError: ''

Fault: ''

Dashboard is empty (for testing purposes I removed all widgets).
Python version 3.8.9, postgreSQL version 12.6.
