ValueError: Expecting : delimiter: line 1 column 19 (char 18)

[TreHat]

Hi everyone,

I am trying to do the Pokemon Go Map of pokemon shown in this video (https://www.youtube.com/watch?v=Io1yeFjVhHQ). I get all the way to the last step perfectly where you enter in the last code so it searches for pokemon locations and get this in my terminal with the "ValueError: Expecting : delimiter: line 1 column 19 (char 18)" appearing on the last line. Any help on how to fix this problem? (Ps. I astriced out my -u and -p but it is correct in the original code.)

Trevors-Air:PokemonGo-Map-master Treavor$ python runserver.py -a ptc -u ****** -p ********** -l "40.1938930, -92.5784320" -st 10
