ZIP to MOBI conversion error

[ToshB]

Just upgraded to Calibre 8.50. I've had no problem with MOBI conversions prior to the upgrade, but now I'm getting this error message when trying to convert ZIP to MOBI. My workflow is exactly the same as it was prior to the upgrade.

Please note: I'm an HTML/Calibre neophyte.

That error report is saying that there is a problem with the input file as it contains invalid data.

Thanks, any idea what it might be?

Where (in what file), your guess is as good as mine, but since it was last seen generating the TOC, I might check those headings that might be detected as TOC entry candidates.

Solved the problem with Time Machine. Went back to previous version and MOBI conversion worked perfectly.

Hey Calibre: if you want people to respond to your beating heart plea for donations, stop fixing what ain't broke!
