Hi @anandbharadwaj1, this seems like a question, and is more suited to ROS Answers.
From the log you've posted, the issue seems to be in the zed_cam repository (I'm not sure where you got it from) and unrelated to this repository.
I'm going to close this off. If you're looking for debugging guidance, please post on ROS Answers, and once you've found the issue, please raise an issue against the appropriate repository. Thanks!
