autodesk forge – Getting Refused to load Scripts Error while running custom visual in PowerBI service in chrome

I am loading a external script in power bi custom visual.

powerbi-visuals-tools version – 4.2.1
powerbi-visuals-api version “5.1.0”,
Getting following error while running custom visual in developer mode in chrome:

Refused to load the script ” because it violates the following Content Security Policy directive: “default-src app.powerbi.com data: blob: ‘unsafe-inline’ ‘unsafe-eval'”. Note that ‘script-src-elem’ was not explicitly set, so ‘default-src’ is used as a fallback.

The js file and CSS file which is mentioned in URL should be loaded. But giving Refused to load script error in console while debugging.
