When the clone model is introduced and added to the AMMO world, the position parameter becomes NaN

[doumuer]

Hello, I have one problem when building a multiplayer online game using three.js+ AMmo.js. The problem is as follows.
When the second player joining the game, the actual position of the model is changed to NaN duiring the clone model being introduced to add to the ammo physics scene with the correct position parameters.
Could you please tell me what is the reason for that? How can I solve this situation?
Finally, attaching the code:

websocket.onmessage = function(evt) {
let obj = JSON.parse(evt.data);
for(var o in obj){
if(o == local_name){

	}else{
		if(!all_player_json.hasOwnProperty(o)){
    		let temp_json = {};
            temp_json['x'] = obj[o]['x'];
            temp_json['y'] = obj[o]['y'];
            temp_json['z'] = obj[o]['z'];
            temp_json['mesh'] = mesh_horse.clone();
            pos.set( temp_json['x'],5, temp_json['z'] );
            quat.set( 0, 0, 0, 1 );
            console.log("newMesh:",temp_json['x'], temp_json['y'], temp_json['z']);
            temp_json['bt_body'] = inputWorld(temp_json['mesh'],pos,quat);
            all_player_json[o] = temp_json;
		}else{
            all_player_json[o]['x'] = obj[o]['x'];
            all_player_json[o]['y'] = obj[o]['y'];
            all_player_json[o]['z'] = obj[o]['z'];
            all_player_json[o]['rotation'] = obj[o]['rotation'];
            all_player_json[o]['directionX'] = obj[o]['directionX'];
            all_player_json[o]['directionY'] = obj[o]['directionY'];
            all_player_json[o]['directionZ'] = obj[o]['directionZ'];
            all_player_json[o]['force_Scalar'] = obj[o]['force_Scalar'];
		}
	}
}
for(var o in all_player_json){ 
    if(!obj.hasOwnProperty(o)){
        removeDebris(all_player_json[o]['mesh']);
        delete all_player_json[o];
    }
}
