Python3 failing to convert str to dict or json

r = requests.get(http_get_url, headers=headers)
r = r.text
r = r.replace("true", "True")
z = json.loads(r)

however, instead of loading the json (or python dict), I get:

Traceback (most recent call last):
  File "/home/noir/PycharmProjects/Work_Projects/get_errors.py", line 21, in <module>
    get_errors(id)
  File "/home/noir/PycharmProjects/Work_Projects/get_errors.py", line 17, in get_errors
    z = json.loads(r)
  File "/usr/lib/python3.6/json/__init__.py", line 354, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python3.6/json/decoder.py", line 339, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python3.6/json/decoder.py", line 357, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 2 column 26 (char 28)

The result of print(type(r)) is <class 'str'>

and the output of print(r) after converting 'true' to 'True' is: 

{
    "HasItemsWithCount": True,
    "Collection": [

            {
            "GroupId" : "14",
            "Time" : "5/16/18, 5:02 PM",
            "File" : "[ESCAPE[]]",
            "Message" : "[ESCAPE[Client was restarted during backup, session may be incomplete.]]",
            "Count" : "3"
            },

    ]
}

So I fail to understand why the correctly formatted string of r fails to import into json.

Also, if I take this output and write it directly into python via copy/paste, the type of the variable is dict, showing me that the text is formatted correctly for a dict in Python. So I'm not sure why json.loads fails.

Your replace is backwards:

Instead of:

r = r.replace("true", "True")

Try:

r = r.replace("True", "true")
