P: Upload to Blurb fails at 50% with Error Message

[Guenther25552765zn58]

Hello everybody, I want to upload a photobook to Blurb, but while uploading it stopped by half upload saying 'An internal error occurred, ?:0: attempt to perform arithmetic on field 'chunk_size' (a nil value)'. How can I upload my photobook? Thanks for your support. Guenther

Got exactly the same problem on a Mac (OS 12.5) today.
Upload to BLURB stopps at 50% with the error message: "?:0: attempt to perform arithmetic on field 'chunk_size' (a nil value)". 
I tried it several times, I made a restart, I disabled the synchronization to my iPad. Nothing helps 😞

I am able to replicate this and will log a bug with the LrC team.

Is it possible that this is a Mac only issue? About 10 days ago I successfully uploaded a small 20 page 10x8" book to Blurb. Win 10, LrC 11.4.1.

 I have been trying to upload a photobook to Blurb, and the upload process fails right after the pages are rendered, and hte actual upload starts. 

The error message is 

trying to perform arithmetic on field 'chunk_size' (a nil value)

Lightroom CC version 11.4

Mac OS Monterey 12.5

Hi,

Can you try to upload the book to Blurb now? The issue seems to be fixed by Blurb at their end. Please try to upload your book and let us know if you are still facing the issue.

Could you please try now? This should be working.

Thanks,
Sunil

Yes, it is working now. I was also advised by Adobe tech support to give Lightroom full disk access. 

So not sure which solution worked (Blurb fixing it on their end, or giving Lightroom full disk access) but bottom line is that it is working now.

Blurb has fixed this on their end and it should be working now.
