Do you know the following Error message?

Error running 'Angular Application' 
# <- the name of the Debug Profile might be named differently in your case
Could not initialize class com.intellij.javascript.debugger.console.jcef.JCE

This happened to us on our WebStorm Cloud Desktop Service.

WebStzorm showing JCEF Error Message after trying to debug the application

It occurs on CentOS systems when you try to debug your application on WebStorm 2022.1 or higher.

The problem was found on:

  • CentOS 7
  • WebStorm 2022.1 and 2022.1.2

The CentOS problem is described here: https://youtrack.jetbrains.com/issue/JBR-4484/JCEF-is-not-supported-in-this-env-or-failed-to-initialize-for-CentOS-7-machine.

Workaround

As a workaround, you can disable the JCEF component by adding ide.browser.jcef.enabled=false in Help | Edit Custom Properties. Then restart the IDE.

This is the advice the superb JetBrains support was giving in no time after issuing the support ticket.

The workaround has been verified on:

  • CentOS 7
  • WebStorm 2022.1.2

Since I have not found the advice anywhere on the Internet, or JetBrain’s pages, I have decided to post the information here. If you find a more official page, please send us a message and we will link to it.

I hope it helps.

Alternative: use vocon’s WebStorm Cloud Desktop Service
