Reflow 3.0 ePub export TOC (RSC-005) error/bug since last update

[chorner11]

Hello,

I'm a professional book designer. Since last Friday's update, all eBooks are exporting with the entire TOC generating (RSC-005) errors--every link. I'm exporting 3.0. I reexported an older project which was good and it has same errors. This is a BUG. I had tech support access my computer, and he says it's not and that Adobe doesn't care about 3rd party verification. However, VENDORS do and have rejected the eBook. 

Can anyone help? My business is dead in the water until this is resolved.

Thank you, Christine

Did this begin after the 20.3.1 patch?

[chorner11]

I do have the 20.3.1 version!

Hi @chorner11,

Thanks for confirming you’re on version 20.3.1. I'm really sorry to hear about the issues with the TOC export. I know how frustrating that must be, especially when it's affecting your ability to deliver work.

This seems similar to an issue discussed in this thread here: Fixed Layout Error RSC-005 – while parsing EPUB file generated from InDesign. Could you please try the suggestions shared there and let me know if it helps?

Looking forward to your update!

Hi, Abhishek,
I created a new book, added the pages, reinstalled the TOC, then exported. Same error. TOC is all RCS-005. I have two eBooks I designed in last 36 hours and both have same problem. Is there code missing I can manually add to a page by breaking into the epub/zip file as a work around until bug is resolved? Or better yet, another solution?

Thank you,

Christine

Hi @chorner11,

Thanks so much for the update. Could you please share a quick screen recording of your workflow showing how you’re exporting the EPUB and where the TOC errors appear?

This will help us better understand exactly what's happening.

Looking forward to your update!

Attached. I then run it through Draft2Digital ePub checker which shows the errors. Per Adobe tech support, I instructed the client to ignore third-party checker and submit to IngramSpark who also showed all of the errors and rejected the file. Thank you for your assistance.

I have the exact same problem, I think. Updated InDesign yesterday, and stumbled over the RSC-005 error when exporting and EPUB 3.0. Screenshot below.

The same file exported without this problem before.

[chorner11]

Yep. I tested and a completed projected and it came back like above.

[Mike Witherell]

I wonder if you could export it from a 20.0 or a 20.1 or a 20.2 version? Would it have the same issues?

[chorner11]

Mike, thank you! I rolled back to 20.1 and the issue is gone! Is a bug for sure.

[matthijssluiter]

Rolling back solved my problem, too. Thanks!

Hi everyone,

Thanks so much for all the details and for sharing the screen captures.

I reached out to the product team, and they've confirmed that the issue with the TOC generating RSC-005 errors has been addressed. The fix is included in our latest pre-release build 20.4.0.25, which has just gone live.

If you're already part of the pre-release program, please try installing the latest pre-release build and let us know if it resolves the issue on your end. If you're not yet enrolled, you can join the pre-release program by following the steps in this guide:
How to join Creative Cloud Prerelease Programs
Or directly here: Invitation to InDesign Prerelease

Once you've had a chance to test it, please let us know how it goes.

Looking forward to your update!

I build my e-books in InDesign from a blank mobile file.

I use the content recovery tool to copy text, images, etc., from my "paper" book to my e-book.

I've always done this, and I've never had a problem.

Today, Epub Checker is giving me a lot of errors (screenshot attached).

So yes, I can take each HTML file and clean it up, but I'd like to understand where the error is coming from?

Can anyone help me, and do you have a faster solution than mine for cleaning up my HTML files?

Thank you very much.
Have a nice day.

Bonjour Anne,

Many are noticing this problem. The bug seems to be in the 20.3.1 version of InDesign. 

Either go back to an earlier version, or update to 20.4. The 20.4 version promises a fix for this code problem.

20.4 is not avaiilable to me here in Florida (yet), so I cannot promise that this is fixed with that patch version.

[Anne Guervel]

Merci beaucoup.
En effet, avec la version précédent mon epub fonctionne très bien, je ne pense jamais à essayer avec une autre version.
Je n'ai pas non plus la 20.4 en France.
Belle journée
Anne

Please read the post from @Abhishek Rao again. This is will be fixed in an upcoming release but if you want it now you can join the prerelease program.

I've had the same issue. Rolling back to 20.0 to get my book out. 

[Paul Nylander]

The problem seems to be the inclusion of a ' target="_blank"' statement in the local link URL.

Removing all instances of the targeting statement from your id-only URLs (e.g. using Sigil or other html editor on the ePub contents) eliminates the problem with validation. Hoping this note saves folks the headaches and uncertainty of installing a pre-release program or rolling back versions.

This worked amazing for me, thank you so much!

Hi,

Before I installed the latest version of Indesign, I was not getting any errors in epub.
After installing the latest version, it started giving footnote errors.
I did not make any changes to my workflow.
I am using the same styles.

I tried the same file with indesign 2023 and 2024. It did not cause any problems.

When I export ePub, pagina checker gives the following warning.

ERROR (RSC-005) at: "SiyeriNebi5.epub/OEBPS/SiyeriNebi-45.xhtml" (satır 91, kolon 650):

Looks like target is not allowed in Epub 3

<a href="chapter2.xhtml" target="_blank">Next Chapter</a>

Try this

<a href="chapter2.xhtml">Next Chapter</a>

or this

<a href="http://example.com" rel="external">External Link</a>

or this

<a href="http://example.com" epub:type="external">External Link</a>

[Roland Dreger]

Hello Ugur,

I can confirm your observation for InDesign 20.3.1. For footnotes, a redundant span element with the attribute “target” is inserted, which results in the validation error.

Is anyone writing a bug report?

Roland
