Sunday Times Teaser 2948 – A Hardy Annual

Published March 24 2019 (link)
Yesterday was my grandson’s birthday and we continued a family tradition. I asked him to use any eight different non-zero digits (once each) to form a set of numbers that added to 2019. Last year I asked the equivalent question with a sum of 2018, and I have done this each year for over ten years. Only on one occasion has he been unable to complete the task.
In this year’s answer his set of numbers included a 3-figure prime that had also featured in last year’s numbers.
(a) In which year was he unable to complete the task?
(b) What was the 3-figure prime that featured in this year’s answer?

If you would like to complete it, i will update your post if you let me have the revised version.
Yes, please do. I have a patched version ready. It gets rid of some variables with no function at all as well as it pays attention to both questions.
