Setting up fake worker failed Error

Hi @kboehmer

I hope you’re well today!

The URL included in error shows that this is related to Hummingbird’s “Asset Optimization”. In general, it means that Asset Optimization configuration needs some tweaking – usually it’s about excluding some assets (JS scripts in this case) from optimization.

The URL that you shared (from error) doesn’t seem to work anymore so I can’t look into it to see what specific JS files it handles (inside every such file there’s a line at the top listing all the JS files such optimize file includes). So in this case I’d suggest switching Asset Optimization (“Hummingbird -> Asset Optimization”) to “Manual” mode instead of “Automatic” – make sure to confirm to keep configuration when prompted during such switch.

You should see a list of CSS and JS files there. Look for all JS files related to PDF Embedder plugin and try (one by one) disabling all optimization options for these files, publishing changes after each one.

Then keep checking for the error and you should see it going away at some point.

Note: while doing that, please make sure not to enable “Don’t load” option for any file in Asset Optimization.

Kind regards,
Adam
