See 28 U.S.C. §§ 1915(e)(2)(B)(ii), 1915A. Because all parties, including unserved defendants, must consent to proceed before the magistrate judge for jurisdiction to vest, Williams v. King, 875 F.3d 500, 503-04 (9th Cir. 2017), we vacate the magistrate judge’s judgment and remand for further proceedings.

VACATED and REMANDED.
