IndexedDB errors in esri demo of IntegratedMeshLayer modification (API 4.16)

[MichaelLev]

When I enter esri demo link for IntegratedMeshLayer modification -

IntegratedMeshLayer modification | ArcGIS API for JavaScript 4.16 

I get in the console multiple identical errors:

dojo.js:115 [esri.views.3d.layers.SceneLayerView3D] Failed to store node in IndexedDB cache: 2755: QuotaExceededError
g._consoleWriter @ dojo.js:115

all errors are identical, except number of cache is different between errros.

1. What is the cause for the error?

2. I want to build WAB custom widget for this capability. Can I ignore the error?

3. What could be done so that the error will not appear?

4. Is it esri issue or that the error depends on my setups?

Attached: screenshot

Help will be greatly appreciated.

Hi,

All your errors are local to your system. as it says 'QuotaExceededError'. this is a browser error. see below on possible fixes.

Workaround

Mozilla Firefox

• Follow instruction from here.

Google Chrome

1. Go to chrome://settings/siteData
2. You should have a list of cookies and website data. Find the arcgis address (for example arcgis.com), click on it to expand stored data and cookies. 
3. You can also click on each item to see how it's size on disk
4. You can also clear this with the 'remove' button, or clear the browser cache completely.

Solved it.

However, it was long ago, and I don't remember now.
