raise JSONDecodeError("Expecting value", s, err.value) from None

[chunshengding]

你好 麻烦想请教一下如下问题
1、报错提示 raise JSONDecodeError("Expecting value", s, err.value) from None
File "D:\工作\cangqiong-scratch-master\main.py", line 29, in get
return json.loads(res.content.decode())
File "C:\Users\ChunshengDing\AppData\Local\Programs\Python\Python39\lib\json_init_.py", line 346, in loads
return _default_decoder.decode(s)
File "C:\Users\ChunshengDing\AppData\Local\Programs\Python\Python39\lib\json\decoder.py", line 337, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\Users\ChunshengDing\AppData\Local\Programs\Python\Python39\lib\json\decoder.py", line 355, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

2、报错代码位置
def raw_decode(self, s, idx=0):
"""Decode a JSON document from s (a str beginning with
a JSON document) and return a 2-tuple of the Python
representation and the index in s where the document ended.

    This can be used to decode a JSON document from a string that may
    have extraneous data at the end.

    """
    try:
        obj, end = self.scan_once(s, idx)
    except StopIteration as err:
        raise JSONDecodeError("Expecting value", s, err.value) from None # 在这里报错
    return obj, end
