Hi @jinleileiking! I believe that this is because the default SDP format is now unified plan, and your offer is in plan-b format. If you want to continue using plan-b, you need to either add SDPSemantics: SDPSemanticsPlanB or SDPSemantics: SDPSemanticsUnifiedPlanWithFallback to your PeerConnection configuration.
