Uncaught ReferenceError: document is not defined;

i need your help thanks

Loading an image while in a worker fails.

Uncaught (in promise) Error: ReferenceError: Image is not defined

Error is caused by image load module, get-pixels. This packages is supposed to work in both Node and browser. The Image class is only accessible with DOM so get-pixel probably uses the browser script while being executed in worker.

Solution: find way to force get-pixels to use it's Node logic to load images. (Not sure if Node scripts like fs will work inside worker.)
