Не работает curl запрос

вот мой curl запрос:

curl -X "POST" "http://127.0.0.1:8000/todo" -H "accept: application/json" -H "Content-Type: application/json" -d "{"id": 1, "item": "cxcadasdas"}"

в ответе же я получаю:

{"detail":[{"loc":["body",1],"msg":"Expecting property name enclosed in double quotes: line 1 column 2 (char 1)","type":"value_error.jsondecode","ctx":{"msg":"Expecting property name enclosed in double quotes","doc":"{id: 1, item: cxcadasdas}","pos":1,"lineno":1,"colno":2}}]}

в чем проблема? везде стоят двойные кавычки
