Invalid timestamp in parameter 'Close Date' (SOLVED)



I keep getting an "Invalid timestamp in parameter 'Close Date' error when creating a deal. My HubSpot timezone is set to UTC -07:00 Pacific Time.

I tried every combination of date, date/time and still can't figure out what HubSpot wants from me.

Any suggestions?
