I'm a bit baffled by the error. Neither job completes. I'm guessing it's related, but it may not be. Any ideas on what's going on?

thanks,

What version of CMS are you running? And do you have multiple languages defined? The Delayed Publish job had a bug in 10 and 11, that were fixed recently.

CMS 10:

CMS 11:
https://world.episerver.com/documentation/Release-Notes/ReleaseNote/?releaseNoteId=CMS-9903

The Link Validator job has had a bug introduced recently, where URLs of unexpected format makes the job crash. I have reported this as a bug (CMS-9930) that has been accepted, but it has not been made public. If you get lucky, you could perhaps exclude some URL patterns and make the job run for the rest of the links. Explaination her:

Thank You! We're using CMS 11.3.2 so we have not gotten the bug fix.

Hi Marcus,

In my opinion, "Object reference error" seems to be related to your content. 

My suggestions:

1. Check the CMS > Reports > Link Status report to see if you find anything there.

2. Check the tblContentSoftLink table in SQL to see if there's something funky going on.
