How to get multiple input fields's values in use state hook

I'm getting an error while controlling an input field which is : "A component is changing an uncontrolled input to be controlled. This is likely caused by the value changing from undefined to a defined value..." and when I try to write something in the input field, it gets back to the state value, here's my code for this

const [inputs, setInputs] = useState({});

useEffect(() => {
    Http.get(apiEndPoint, {
      params: {
        email: user.userEmail,
      },
    }).then((res) => setInputs(res.data));
  });

const handleChange = (e) => {
    setInputs((prevState) => ({
      ...prevState,
      [e.target.name]: e.target.value,
    }));
  };

These are two of the several input fields,

<Row>
               <Col className="pr-1" md="6">
                  <Form.Group>
                    <label>First Name</label>
                    <Form.Control
                      name="firstName"
                      onChange={handleChange}
                      type="text"
                      value={inputs.firstName || ""}
                    ></Form.Control>
                  </Form.Group>
                </Col>
                <Col className="pl-1" md="6">
                  <Form.Group>
                    <label>Last Name</label>
                    <Form.Control
                      name="lastName"
                      onChange={handleChange}
                      type="text"
                      value={inputs.lastName || ""}
                    ></Form.Control>
                  </Form.Group>
                </Col>
              </Row>

Have useEffect triggered during initial rendering. Then it won't be triggered every re-render and change the state to its initial values.

useEffect(() => {
    Http.get(apiEndPoint, {
      params: {
        email: user.userEmail,
      },
    }).then((res) => setInputs(res.data));
  },[]);
