error in player_compiled.js: Uncaught (in promise) DOMException: play() failed because the user didn't interact with the document first.

I am inheriting the output of a project built with what appears to be an old version of Storyline.

My copy of player_compiled.js says this at the top:

var buildNumber=65;var buildDate="20170505 14:09"

When I click on a link that goes directly to a storyline page/video, I see this error in the developer console:

Can anyone explain what this error means and what I might do to resolve it?

Must I upgrade my copy of storyline somehow?

Can I upgrade my output files w/o having the full project/input files?
