在服务器上添加夹具时出现反序列化错误(loaddata)

我正在尝试将数据添加到服务器的数据库中。我使用完全相同的 JSON 文件在我的本地机器中,它可以正常工作。但当我在服务器上做同样的事情时 Deserialization Error .

这个 JSON 文件太大了,我不能在这里显示,但我确信没有输入错误。

我完成了所有迁移和数据库工作-我可以从管理仪表板添加对象。如何解决此错误?

我得到的错误:

    Traceback (most recent call last):
  File "/home/testuser/myprojectt/myvenv/lib/python3.8/site-packages/django/core/serializers/json.py", line 69, in Deserializer
    objects = json.loads(stream_or_string)
  File "/usr/lib/python3.8/json/__init__.py", line 357, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python3.8/json/decoder.py", line 337, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())

    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

The above exception was the direct cause of the following exception:

已检查 JSON 一次又一次,但它仍然在本地工作,但在服务器上出现相同的错误。
