Hi, 

I tried in our practice system and I didn't encounter the same error as you did.

Can you check the data (SchedldBasicEarliestStartDate) of the first two entries from SE16? Probably it's due to some erroneous data. Also, can you exclude the date field from the response by specifying a select query option? And see if you still get the error?
