Datsehift function "Shift to Weekday" yields error message

The following code provided by MathWorks does not work

https://ch.mathworks.com/help/matlab/ref/datetime.dateshift.html#bugshus-1

t = [datetime(2021,5,30) datetime(2021,6,4)];
t.Format='eeee, dd MMM yyyy'
t2 = dateshift(t,'dayofweek','weekday')

I obtain the following error message:

Error using datetime/dateshift (line 151)

Day of week must be a number from 1 to 7, or a day name. Any idea why this error occurs?
