@harmeeksinghbedi Are you still facing this issue? If so could you give some more context on the issue? Does the error happen under a certain set of circumstances? What version of CARLA are you using?

@jackbart94 Could you follow up please?

[jackbart94]

Unfortunately, without any way to reproduce this, I can't debug it. We would need more information.
