TypeError: layout.getGraphRect is not a function

I am getting this error when trying to use the offline layout here is my code snippet

let offlayout = Viva.Graph.Layout.offline(this.graph, {
      terations: 100, // Run `100` iterations only
      saveEach: 10, // Save each `10th` iteration
      outDir: './cache', // Save results into `./cache`
      layout: require('ngraph.forcelayout3d') // use custom layouter
    });

i also tried to do this

let layout = Viva.Graph.Layout.forceDirected3d(this.graph, {
      springLength: 30,
      springCoeff: 0.0008,
      dragCoeff: 0.01,
      gravity: -1.2,
      theta: 1
    });
    let offlayout = Viva.Graph.Layout.offline(this.graph, {
      terations: 100, // Run `100` iterations only
      saveEach: 10, // Save each `10th` iteration
      outDir: './cache', // Save results into `./cache`
      layout: require('ngraph.forcelayout3d') // use custom layouter
    });

Same problem
