DeserializationError when adding fixture on server (loaddata) - django

Question

I am trying to add my data to database in my server. I use exactly the same JSON file in my local machine and it works. But when I do the same in server it gives me Deserialization Error.
The JSON file is so big that I can't show it here but I am sure there is no typo.
I did all migrations and database works - I can add object from admin dashboard. How can I solve this error?
The error I get:
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)

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:

django.core.serializers.base.DeserializationError: Problem installing fixture '/home/testuser/myprojectt/myprojectt/articles/fixtures/article.json':
Checked the JSON again and again but it still working on local but the same error on server.

Answer 1

I am using Ubuntu on the server. And didn't have git-lfs installed. To solve this issue:
Install it with sudo apt-get install git-lfs.
Then run git lfs pull on project directory.
And then I managed to work with the JSON data as I wanted.
