Spot the bug - #116: Text Search Result

Help me catch this sneaky regex bug.

function findLostPearls(text) {
  const pearlRegex = new RegExp("\bpearl(s)?\b", "g");
  return text.match(pearlRegex);
}
const treasureMap = "Many pearls scattered. A single pearl lies here. No perls!";
console.log(findLostPearls(treasureMap));
