Hello,

I just upgrades from 4.11 to 4.18 and i got an issue that a cannot figured how to resolve.

I can reproduce it by two different ways:

When creating a polygon with the sketch widget. After my first click on the map, the error occurs and the sketch is cancel.

this.sketch = new Sketch({ layer: this.sketchLayer, view: this.view, creationMode: 'single', }); this.sketch.create('polygon');

When using the DistanceMeasurement2D. The error occurs when the measurement is completed.

const widget = new DistanceMeasurement2D({ view: this.props.view }); widget.viewModel.unit = this.state.currentMeasurementUnit; widget.viewModel.mode = 'geodesic'; widget.viewModel.newMeasurement();

Uncaught (in promise) TypeError: Cannot read property 'items' of null
at g.P._getGraphicsToUpdate (mapViewDeps.js:685)
at g.P._updateGraphics (mapViewDeps.js:686)
at g.P._updateGraphics (mapViewDeps.js:689)

Any idea how i can fix it?

Thanks

Jerome

Hello,
Would you be able to provide a reproducible codepen?
I tried the workflow with the Sketch widget you provided, and could not reproduce the issue in 4.18.
Take a look at this codepen:
