The Economist recipe does not work

[gc886]

I have been using the recipe for The Economist for years and never had any problem. Today it seem to have failed due to a TypeError. I am running version 7.12.0, not the latest, and I am not sure if I need to update to the latest Calibre version to make this work. Is anyone else also experiencing this and is there any workaround?

Update calibre and you will be fine or wait an hour and retry and you will be fine.

Thank you! The recipe works now!

I am still having issues with the Economist download. It seems to error out at the end after downloading a significant percentage of the file.

That error just means you will have some missing images. It looks like for some reason the economist servers are throttling you, I just tried downloading the economist and it worked fine with no errors for me. Are you sure you are using the builtin recipe?
