how fix it? on windows is work, but on linux have error!

[nlohmann]

Your input is invalid JSON. It seems an opening brace for the object is missing. There should also be an error on Windows.

[nlohmann]

Do you need further assistance with this issue?

@nlohmann : I have a similar issue. My json file contains:
{"Anna" : {
"age": 18,
"profession": "student"},
"Ben" : {
"age" : "nineteen",
"profession": "mechanic"}
}

Below is the code:
nlohmann::json pointsTest;
string pointsFTest = "Resources/sample.json";
ifstream pointsFileTest(pointsFTest);
cout<<"PRINTING OUTPUT"<<pointsFileTest.rdbuf()<<"*********"<<endl;
pointsFileTest >> pointsTest;

The output has been printed succesfully. However, deserializing gives below error.
terminate called after throwing an instance of 'nlohmann::detail::parse_error'
what(): [json.exception.parse_error.101] parse error at line 1, column 1: syntax error while parsing value - unexpected end of input; expected '[', '{', or a literal
Aborted (core dumped)

You try to read the file twice. That does not work.

@nlohmann : Thanks!
