Web Worker Failing on Chrome

brucem1976 commented 5 years ago

Chrome 75.0.3770.100 Win 10 64-bit

I do the following:

var compressionOptions = {
          maxSizeMB: 0.8,
          maxWidthOrHeight: 1920,
          useWebWorker: true,
          exifOrientation: true
        };
const imageFile = await imageCompression(
          file,
          compressionOptions
        );

and get the following in browser console:

browser-image-compression.mjs:430 Run compression in web worker failed: x is not defined , fall back to main thread

Any ideas what could be wrong? The image is correctly compressed, but without a web worker.

I notice the same issue on Firefox.

For now I'm setting useWebWorker to false, which won't fix the issue of course but the warning will be suppressed.

A previous closed issue https://github.com/Donaldcwl/browser-image-compression/issues/15 confirmed that Web Workers don't work in Firefox, but this is specifically about Chrome

@brucem1976 The logging in the production script seems not enough to debug. Can you use this script and see the console again? debug script.zip

Thanks.

@Donaldcwl i m having an issue when my browser adblock on chrome is turned ON , i get this error in console.

Refused to create a worker from 'blob:https://site.com/3e9ce499-7750-4d8c-896b-7db16d4677c6' because it violates the following Content Security Policy directive: "script-src 'self' * 'unsafe-inline'". Note that 'worker-src' was not explicitly set, so 'script-src' is used as a fallback.

Any way to fix this, i have even turned off use web worker option by false.

There should be no problem in v1.0.7
