Calibre not creating .apnx files when sending to device

[Xeno_Xenon_]

I googled this issue and found this thread :https://www.mobileread.com/forums/sh...=257804&page=2
i confirmed i got the same problem that Calibre did not find the path, but the answers didnt seem to have given a solution.
Can anybody help me with this?

Do you have the option to send page number information enabled under customize this device? If so then run calibre in debug mode (right click preferences) and post the log generated when you send a file to the device.

Sorry but looks like my PC got a problem. Will get it back online ASAP.
But before that, I can tell that I actually tried to get into debug mode and check the log after reading the post i linked above. It showed a similar "path doesn't exist" message.
Hope you can help me with these clues, still working on my PC. I will get the log ASAP if you still cant.

New to the forum,I thought there was something wrong when my reply didnt show up.
Great, so there's no need to worry about my computer

Your problem is APNX generation is failing. See the line:
Failed to generate APNX

But your log doesn't contain the traceback for the failure are you sure you posted the full log?

Found traceback under the "Starting Quick view" line
Is that what you are looking for?

[kovidgoyal]

Yes, that traceback indicates the filename is too long. Shorten the book title and you will be fine.

Do I need to change the metadata or just change the title showed in calibre?
Or can i fix the issue by changing the "send to device" settings to rename the files sent to the device and change the title in the filename to something else?

[kovidgoyal]

Just change the title in calibre or change the template, either will work.
