Uncaught TypeError: Failed to execute 'importScripts' on 'WorkerGlobalScope': Module scripts don't support importScripts()

Hi Team,

I faced with importScripts problem after upgrading from version 1.108 to version 1.109.
I use a CDN version of Cesium.

I prepared a simple example to reproduce the problem.
Just check the browser console.

Sandcastle example:

• not reproduced on Sandcastle but reproduced in the simplest example – https://aerialist7.github.io/cesium-sample/
• source code here – https://github.com/aerialist7/cesium-sample

Browser:

• Chrome 116.0.5845.140 (Official Build) (arm64)

Operating System:

• macOS 13.5.1 (22G90)

@ggetz, hi! Could you please have a look?
It looks like it's related to this change #11400

Thanks for reporting this @aerialist7. We're taking a look now. This appears to be an issue with cross-origin workers specifically - In this case between https://aerialist7.github.io/ and the CDN.

@aerialist7 I have a branch, worker-inline, which should resolve issues with the cross-origin workers.

Could you try http://cesium-dev.s3-website-us-east-1.amazonaws.com/cesium/worker-inline/Build in place of https://cesium.com/downloads/cesiumjs/releases/1.109/Build/?

@ggetz, there is a problem with HTTP:

Do you have an ability to deploy fixed version somewhere under HTTPS?

UPD: It works under HTTP locally

I encountered the same issue when running Quickstart, and the browser console displayed these errors:

After replacing the src of the script tag with this link, the issue was resolved.
