terminate called after throwing an instance of 'std::invalid_argument'

[nvhungv2k]

I am trying panther on Ubuntu 18.04 and ros-melodic
I've completed procedure to build and install panther and it's dependencies.
I proceeds to run: roslaunch panther simulation.launch quad:=SQ01s
And panther-node died immediately as following image:

After that, I run panther-node in separated terminal: rosrun panther panther_node ~state:=state ~who_plans:=who_plans term_goal:=term_goal ~trajs_predicted:=tracker_predictor_node/trajs_predicted ~traj:=traj ~trajs_zhejiang:=trajs_zhejiang ~goal:=goal ~setpoint:=setpoint __name:=panther
I thrown this error:
"terminate called after throwing an instance of 'std::invalid_argument'
what(): stoi
Aborted (core dumped)"

我正在 Ubuntu 18.04 和 ros-melodic 上试用 panther，我已经完成了构建和安装 panther 及其依赖项的过程。我继续运行： Panther-node 立即死亡，如下图所示：之后，我在单独的终端中运行 panther-node：我抛出这个错误：“在抛出 'std：：invalid_argument' 的实例后终止调用：stoi 中止（核心转储）”roslaunch panther simulation.launch quad:=SQ01s``rosrun panther panther_node ~state:=state ~who_plans:=who_plans term_goal:=term_goal ~trajs_predicted:=tracker_predictor_node/trajs_predicted ~traj:=traj ~trajs_zhejiang:=trajs_zhejiang ~goal:=goal ~setpoint:=setpoint __name:=panther

请问下最后是怎么解决的
