KB486138: “Visualization type Map (ESRI) is blank on a particular Web browser, and on Browser Developer tools the message WEBGL is required but not supported.’’

Starting with the release of Strategy ONE (March 2024), dossiers are also known as dashboards.

Symptom

When creating a new Dossier on Library, a Map (ESRI) visualization is shown blank.

Cause

To determine the root cause, the Browser Developer console can be used. Based on the browser, the following links can be used to access this tool:

• Chrome: Open Chrome DevTools
• Firefox: Firefox DevTools User Docs
• Edge: Overview of DevTools

If the following message can be seen: (esri.views.MapView) #validate () WebGL is required but not supported.

The next webpage can be used to see if the error message received is the same or similar https://developers.arcgis.com/javascript/latest/sample-code/custom-gl-visuals/

On the image the following error can show: 
WEBGL2 is required but not supported.

WebGL stands for Web Graphics Library. It is a JavaScript API for rendering interactive 2D and 3D graphics within any compatible web browser without the use of plug-ins. The availability of WebGL is dependent on GPU (Graphics processing unit) support, on some older devices the usage of a GPU might be impossible.

Sometimes, WebGL cannot work as expected on the web browsers because they might be not up to date.
 

Action

To solve this issue, go to your browser’s settings:

• for Chrome: chrome://settings/help 
• for Edge: edge://settings/help 

and update your browser accordingly.

Then restart your browser and see if the error persists.
If the error persists, disable your browser Extensions, and see if the error persists. If the error is not persisting anymore, then you can start enabling one by one the Extensions to find which is the one causing the problem.
