Actually, I am not so sure if the file I choose is correct, Kobo.sqlite. I tried every other file, only this make sense. however it returned errors. File location is ~/Library/Application Support/Kobo/Kobo Desktop Edition/

Hi @NTU-Sherlock,

I had a brief look at the logs you shared and it seems that highlights in that database are detected but one or more fields it expects to find populated is missing.

It could be say; a book missing an author for example but I can't really say without having a look at the database directly.

I've never tried to run a database created by the Kobo Desktop App through October as it was never designed to work with it, just regular physically connected Kobo devices.

If you don't have a real Kobo and you're just using the desktop app for store purchased books, you should be able to use the official Readwise integration (that only works with the Kobo store) unless you're having trouble with it?

[NTU-Sherlock]

Yes, I do have trouble with it. The syncing is not smooth, sometimes I have to disconnect and reconnect. However, this book always failed to sync, that's why I have to tried October.

[marcus-crane]

I've installed Kobo Desktop Edition and I seem to have a similar issue (specifically that no highlights appear but I might find more as I get further in) so I'll do some debugging and see what's required to support the desktop version.

I'm not hugely surprised that it doesn't work out of the box as there are no guarantees that the Kobo's internal database file matches the desktop version and October had never been developed with the desktop client in mind.

The exact layout of the database mostly stays the same but does slightly change over time as new devices are released.

Hi Marcus,

Thanks for the response.

Do you think using iPhone Kobo app would make any difference? Or I must connect with Kobo E-reader?

[NTU-Sherlock]

Hi Marcus,

I successfully Sync from Kobo official connections with Readwise.

This is what I did: As shown in first post. The problem a specific books error- 一如既往, which is the one missing from readwise.

Then I review my notes on Kobo, I found out there is a typo "zhuyin" (looks like ㄩ） in my note, so I deleted it. I also delete some empty notes, (looks like " ")

Then I tried re-sync again, the notes is import from Kobo to Readwise without a problem.

Thank you very much!

Hey there,

Do you think using iPhone Kobo app would make any difference?

I've never tried using the iPhone app and then seeing what the resulting database looks like. October was never designed to work with anything but actual Kobo eReader devices. If other devices like the desktop app work, it's only be coincidence and not by design although I'm not opposed to adding support, depending on what is involved.

I successfully Sync from Kobo official connections with Readwise.

Ah, great! I haven't looked into the issue any further as I have a lot of life stuff on at the moment so I haven't had much time at home

Thanks for the update and I'll post here when I get around to looking into the issue further.
