Hi community, I need some help to figure out the server tool for designer.

I configure it with what I think are correct fields.

And I get this error.
Error: Server API (13): Tool #683: Traceback (most recent call last):
File "C:\ProgramData\Alteryx\Engine\Engine_9820_205b358badde45b2bd7f0802d20d2ac4_\8258b1967a2eec3608e74e0c1eebae59\workbook.py", line 84, in <module>
token['expires_at']=dt.datetime.utcnow()+dt.timedelta(0,token['expires_in'])
KeyError: 'expires_in'
Any ideas?
