json decode error(warning)

[alan000322]

When I tried the following codes, it jumped out "json.decoder.JSONDecodeError: Expecting value: line 1 column 2 (char 1)".

for post in get_posts("nintendo", pages=3, cookies = cookies/facebook.com_cookies_1.txt", options={"reactors": True}  ):
    print(post)
    break

I think it's just a warning sign, but I was still confused about why it jumped out the errors.

Thanks!
