buttons for direct command sending

Hello everyone, I'm trying to implement 2 buttons to turn the engine on and off, through the device popup, but I must be missing some detail, because I got the error 404 Not Found. Any idea? Thanks

const [loading, setLoading] = useState(false);

  const handleBlockMotor = async () => {
    setLoading(true);
    try {
      await axios.post('/api/command/send', {
        type: 'engineStop',
        attributes: {},
        deviceId: 14,
      });
    } catch (error) {
      error(error);
    } finally {
      setLoading(false);
    }
  };

  const handleUnblockMotor = async () => {
    setLoading(true);
    try {
      await axios.post('/api/command/send', {
        type: 'engineResume',
        attributes: {},
        deviceId: 14,
      });
    } catch (error) {
      error(error);
    } finally {
      setLoading(false);
    }
  };
.
.
.
<div>
<Button onClick={handleBlockMotor} disabled={loading}>
Block Motor
</Button>
<Button onClick={handleUnblockMotor} disabled={loading}>
Unblock Motor
</Button>
</div>
