JSON load function gives Extra Data value error

When I read JSON file it gives me following error:

json.decoder.JSONDecodeError: Extra data: line 16043 column 2 (char 370886)

This error seems to be valid as json.load does not decode multiple json objects and my JSON contains 2 or more objects.

{ "log": [ 
 {
   "code": "info",
   "message": {"text": "[info] Activation of plug-in abcd rule processor (xule) successful, version Check version using Tools->Xule->Version on the GUI or --xule-version on the command line. - xule "},
   "refs": [{"href": "xule"}],
   "level": "info"
 }

   "refs": [{"href": "xule"}]


}]}

I came across this article for resolution: Python json.loads shows ValueError: Extra data which says I need to add my log dictionaries in json.dumps() prior to json.loads(). But, I am unable to get it done. Please can anyone help me.

This is my python code:

with open('C:/Users/Desktop/SampleTestFiles/logfile.json', encoding="utf-8") as json_file:
    data = json.load(json_file)

according to jsonlint:

Error: Parse error on line 27:
...le"          }]      }   ]} {    "log": [{           "cod
------------------^
Expecting 'EOF', '}', ',', ']', got '{'

In other words , you have 2 jsons in one, should be a list, as in 

[{
        "log": [{
                "code": "info",
                "message": {
                    "text": "[info] Activation of plug-in abcd rule processor (xule) successful, version Check version using Tools->Xule->Version on the GUI or --xule-version on the command line. - xule "
                },
                "refs": [{
                    "href": "xule"
                }],
                "level": "info"
            },
            {
                "code": "xyz.F1.all.7",
                "level": "error",
                "message": {

                },
                "refs": [{
                    "href": "xule"
                }]

            }
        ]
    },
    {
        "log": [{
                "code": "info",
                "message": {
                    "text": "[info] Activation of plug-in abcd rule processor (xule) successful, version Check version using Tools->Xule->Version on the GUI or --xule-version on the command line. - xule "
                },
                "refs": [{
                    "href": "xule"
                }],
                "level": "info"
            },
            {
                "code": "xyz.F1.all.7",
                "level": "error",

                },
                "refs": [{
                    "href": "xule"
                }]


            }
        ]
    }
]

TRY SOMETHING LikE:


import json

mylist = []
with open('C:/Users/Desktop/SampleTestFiles/logfile.json', encoding="utf-8") as f:
    new_el = ''
    for l in f:
       new_el += l.rstrip('\n')
       try:
          sub = json.loads(new_el)
          mylist.append(sub)
          new_el = ''
       except:# json.decoder.JSONDecodeError:
          pass
print(mylist)

This prints: [{u'log': [{u'message': {u'text': u'[info] Activation of plug-in abcd rule processor (xule) successful, version Check version using Tools->Xule->Version on the GUI or --xule-version on the command line. - xule '}, u'code': u'info', u'refs': [{u'href': u'xule'}], u'level': u'info'}, {u'message': {u'text': u'[xyz.F1.all.7] The value for ForResale with a value of 63 has a unit of utr:MWh.
