Cannot read property 'node' of undefined

I have 2 different Vue projects wich both use handtrackjs. The components which use handtrackjs are identical. In the newer project i get the following error:

Uncaught (in promise) TypeError: Cannot read property 'node' of undefined

at eval (webpack-internal:///./node_modules/@tensorflow/tfjs-core/dist/tf-core.esm.js:250)

Whereas in the old project everything works as expected. Both projects use the same handtrackjs version + same Vue version. Is there any hint what might cause this behaviour?

I have the same issue. Here is a component made quickly as test:

<template>
<canvas ref="canvas" style="background: green;"></canvas>
</template>
<script>
import Vue from 'vue';
import {
  Component
} from 'vue-property-decorator';
import * as handTrack from 'handtrackjs';

@Component({
  name: 'AirControl',
  data() {
    return {
      model: null
    };
  },
  async mounted() {
    this.model = await handTrack.load();
    console.log('model loaded');
  }
})
export default class AirControl extends Vue {}
</script>

Result: same error as the initial post. I don't even see the model loaded log message.

Note: I use tensorFlow 2.7.0.

Any update ?
