Error getting token part 2

[tpcolson]

Similar to #280, I'm getting

Traceback (most recent call last):
File "C:\Temp\NEXRAD_PYTHON\update-Tiles-From-TPK\update-Tiles-From-TPK\OverWriteTilePackage.py", line 83, in
token= getToken(user, pw)
File "C:\Temp\NEXRAD_PYTHON\update-Tiles-From-TPK\update-Tiles-From-TPK\OverWriteTilePackage.py", line 26, in getToken
return jres['token'],jres['ssl']
KeyError: 'token'

{"error":{"code":400,"message":"Unable to generate token.","details":["'username' must be specified.","'password' must be specified."]}}

Despite using the same, correct username and pw that I can login to AGOL successfully, so the issue IS NOT incorrect username or pw.

the issue IS NOT incorrect username or pw.

the error seems to indicate that a username and/or password aren't making it through in the request at all.
