What is your rationale for making the footnotes artifacts? Presumably the footnotes provide information, and that information should be available to assistive technology users as well as users who experience the visual representation of the document. Link annotations cannot be marked as artifacts, and will cause the error that you are experiencing. Please consider tagging the footnotes as real content.

Hi a "C" Student,
Sorry I was not talking about footnotes, I mean footers.
The footers are repetitive in the section on over 100 pages.
From my understanding, the first repetitive footer/header should be tagged but the rest should be artifacts.
I have made them artifacts but I want the links remained in the PDF to be clickable,
however if I do not tag them as Link it will create "Tagged Annotations - Failed" error.
Ah, OK. Unfortunately I do not know of a good solution for this common problem. The usual advice is to not put links in repeating footers. But for the most part I do not own the documents I remediate, and if the document owner insists on a link in the footer I have to find a way to deal with it. A clunky, kludgey fix is to include the link annotation in the tag structure, but hide it under a <Span> tag with a space character for Actual Text. Or, live with the error if that is an option. Sorry - that's the best I've got.
