Error load Json data array from Php in Python

I have this data of array in php that converted to json

$dataraw = $_SESSION['image'];
$datagambar = json_encode($dataraw);
$escaped_json = escapeshellarg($datagambar);

Escaped_json output as strings:

"[{ FileName : 20221227_202035.jpg , Model : SM-A528B , Longitude :106.904251, Latitude :-6.167665},{ FileName : 20221227_202157.jpg , Model : SM-A528B , Longitude :106.9042428, Latitude :-6.167658099722223}]"

Datagambar output as array :

[{"FileName":"20221227_202035.jpg","Model":"SM-A528B","Longitude":106.904251,"Latitude":-6.167665},{"FileName":"20221227_202157.jpg","Model":"SM-A528B","Longitude":106.9042428,"Latitude":-6.167658099722223}]

I want to call it to python, this is my py code

escaped_json = sys.argv[1] 
parsed_data = json.loads(escaped_json) 
print (parsed_data[0])

But from parsed_data = json.loads(escaped_json)
I get an error JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Is there any suggestions how to fix it?
