Failing to find covers in calibre

zielin · 07-16-2022, 05:42 PM

Hi there,

I come to see you because I have a problem with calibre, I can't download the covers. Each time the search fails.

If anyone has an idea to solve this problem I would be very grateful.

Thanks in advance.

Here is the part of the error report that seems to be the problem:

"Traceback (most recent call last):
File "calibre\ebooks\metadata\sources\amazon.py", line 381, in run
File "calibre\ebooks\metadata\sources\amazon.py", line 387, in get_details
TypeError: cannot unpack non-iterable NoneType object

No cover found"

I'm having this issue. I'm guessing it's a cookie permission thing.

Is there a fix for this for 6.29? my mac can't upgrade to a newer version.

Have you tuned (or overtuned) your Get Metadata sources?

By 'over tuned', You have so tightened where the PI can look that very few make the grade.
Another thing that blocks is wrong existing metadata. Your Book is French, but you have English as its language in the MDE . A wrong ISBN is worse than no ISBN.

And for Updating Existing covers (outside the MDE): Search the Internet plugin: <pick the Image source from the GUI>
