Api Request using Http request for get method. but don't know actual problem in Flutter

I am new in flutter and learning api request. I make a request for get method. but it shows error! i can't receive any data!

In Postman, it works fine and data comes properly!

This api and token is only for test porpuse! so, don't worry!

Api request

Future fetchAlbum() async {
  final token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjI4OTksImlzcyI6Imh0dHBzOi8vcG9ydGFsLWFwaS5qb21ha2hhdGEuY29tL2FwaS9hdXRoL2xvZ2luIiwiaWF0IjoxNjMxMjUxNjYwLCJleHAiOjE2MzEzMzgwNjAsIm5iZiI6MTYzMTI1MTY2MCwianRpIjoiNlFEUTZCYnBMT0JhdUJoaSJ9.jAY_2nYxjgsIvXZY5vn0vAr_pwF6UBYbSGZ8wqD0YPQ';
  final response = await http.get(
    Uri.parse('https://portal-api.jomakhata.com/api/getLeaveDetails?token=${token}'),
    // Send authorization headers to the backend.
  );
  final responseJson = jsonDecode(response.body);

  if(response.statusCode==200){
    print("ok");
    print(responseJson);
  }
  else{
    print("error!");
  }

  return responseJson;
}

Error in Console

There is an error in the API endpoint you are calling, more precisely there is an SQL error SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'url' at row 1.

Because of this, an error message is inserted into the JSON output, like this:

}{
    "message": ...

This is not a problem for Postman to display, but as a result you get an invalid JSON, there should be a , between { and }.

So when you try to decode it in Flutter, you will get an error, because conversion fails: Unhandled Exception: FormatException: Unexpected character.
