It wasn’t a very important lie. It was of no consequence to the FBI or the special counsel’s investigation. Papadopoulos was such an afterthought that the Bureau did not bother to interview him until late January 2017 — about 10 months after he met Mifsud. By the time Papadopoulos was charged, the Trump–Russia investigation had been ongoing for well over a year — it was already clear that there was no conspiracy.
