Embedded thumbnail images missing on HTML exported space

Question

Running a newly-installed on-premises version of Confluence 6.8.1

When viewing a page in the browser from the live confluence server, the thumbnail for an attached file (in this case, a PDF) appears as you'd expect:

See below for example

However after exporting the site to HTML, the same page shows a broken image placeholder for the thumbnail:

The Image Source path for the missing image points to an entire path (/rest/...) that does not exist in he exported HTML package:

<SPACENAME>/rest/documentConversion/latest/conversion/thumbnail/9895997/

There are no special themes, HTML modifications or anything else running in this instance - it is a rather vanilla install.

Thoughts??

Thanks Zak - i've upvoted the bugfix.  Unfortunately a manual export won't work - we produce an export with 200+ individual pages, each of which has several embedded PDFs, so we do need it to work in an automated fashion.

Hi Dave,

I did some testing and was able to reproduce the same behavior. Unfortunately, this is a known bug we have documented in a ticket open with our developers: CONFSERVER-36638. Feel free to vote and comment on this bug ticket to help give our developers more context around the issue (see also: Atlassian Bug Fixing Policy).

In the meantime, the best workaround I can see would be to manually save the thumbnail from the live page to include it on the HTML export. I know it's not ideal, but it's the best workaround to avoid a broken thumbnail image on the page. If you're exporting to import into another Confluence instance, you can also try an XML export.
