I bid 2C with 23 HCP and a balanced hand. Responder has 1 HCP with a 5-card minor.

Auction proceeds ... 2D 2N. Then responder bids 3N, which according to its description 3-8 HCP which is what I would expect. Actually I would hope for a bit more than 3 as one-sided 3N contracts on minimum points are often tricky.

However very surprised to see robot has only 1 HCP and no easy entries. Contract goes down 2.

Robot must pass 2N surely?

3NT explanation says "2-5C; 2-5D; 2-4H; 2-4S; 3-8 HCP"

Are you sure it doesn't say TP somewhere?
Anyways Gib usually counts shortness even in NT, even when in partner's suit even when playing in partner;s suit. Also, it is not uncommon for Gib to be well outside the range of the description.
Even with this pile of dreck on a non-club lead there is some chance to make 3N but your right is not a good bid.
