pixel_player58064059 have you tried not buying the ship? The only other suggestion is to grab a screenshot of the offer and the error message and submit them via their in-game support mechanisms.
Since you just joined the forum I'm going to assume that you got here via their support web site. If so, scroll further down, select a category, and file the report that way. This is mostly a player forum so there's no PF support personnel here to help you resolve this.
