Python: `python DT22logger.py` error using PUTTY

Question

I have done configuring some of the commands in making the DHT22 Temperature Sensor work.

I have done configuring some codes in config.json now I am up to this python DHT22logger.py but I am getting this error (refer below)

Traceback (most recent call last):
  File "DHT22logger.py", line 422, in <module>
    main()
  File "DHT22logger.py", line 251, in main
    configurations = getConfigurations()
  File "DHT22logger.py", line 243, in getConfigurations
    configurations = json.loads(open(configurationFile).read())
  File "/usr/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 21 column 2 (char 347)

There is a tutorial that I have been following, when he write this python DHT22logger.py no errors, and the datas are in there. But in my case none.

Answer 1

There is an error in your configuration file.

Python, rather helpfully, tells you where.

line 21 column 2 (char 347)
