ValueError: No JSON object could be decoded in python

问题

I followed the instruction on the post to convert the shape file into a jvector map, I have downloaded the shape file from this site.

Below is the content of my bat file.

python converter.py ^
New_South_Wales.shp ^
test-map.js ^
--width 400 ^
--where "ISO_3166_2 = 'AU-' and code_hasc!=''" ^
--country_name_index 12 ^
--country_code_index 18 ^
--minimal_area 4000000 ^
--buffer_distance -0.5 ^
--simplify_tolerance 10000 ^
--longitude0 25.2744 ^
--name nsw

My folder contains the below files

I am getting the below error in command prompt when executing the bat file.
