UAPI: SyntaxError in JSON.parse

I want to get the JSON results of UAPI and parse it in my Python program. It seems there is something wrong with the JSON output of the api. I run the following command: 'uapi --user=myuser --output=json Bandwidth query grouping=year_month' and get the results: {"apiversion":3,"module":"Bandwidth","func":"query","result":{"data":{"1514752200":263337219892,"1543609800":145884299586,"1538339400":119656400553,"1541017800":172890529729,"1519849800":114107934353,"1546288200":88071820650,"1527795000":132312176767,"1509481800":313760720498,"1517430600":115307443541,"1504207800":508826138914,"1535743800":123868059627,"1501529400":48003795128,"1533065400":126802068190,"1522524600":121649274903,"1506803400":314056226618,"1525116600":135102301157,"1530387000":139453841103,"1512073800":237340430641},"warnings":null,"status":1,"messages":null,"errors":null,"metadata":{}} But when I want to parse the results I get the following error in Python: json.decoder.JSONDecodeError: Expecting ',' delimiter: line 2 column 1 (char 609) and of course on Mozilla Firefox I get the following error: SyntaxError: JSON.parse: end of data after property value in object at line 2 column 1 of the JSON data
