Update 6.6 minor error

After update to 6.6, when calling the “supply stock” wizard this error message occurs:

TypeError: fromisoformat: argument must be str

Fault: fromisoformat: argument must be str

What should I do?

Cheers,

Check the bugtracker: Issue 11895: fromisoformat: argument must be str when compute quantities grouping by date with move without date - Tryton issue tracker

Thank you - looking forward to the solution.
