Cannot read properties of undefined (reading 'getHyperCubeData')

[deliciouscake]

Hi, im very new to qlik.

I am trying to retrieve data from a table, I heard the best way to go about this is by using getHybercubeData.

  useEffect(() => {

    let qObject;

    const result = qObject.getHyperCubeData({

      qPath: '/qHyperCubeDef',

      qPages: [

        {

          qLeft: 0,

          qTop: 0,

          qWidth: 5,

          qHeight: 100,

        },

      ],

    });

    console.log(result);

  }, []);

However im getting an error stating 'Cannot read properties of undefined (reading 'getHyperCubeData')
