The rosbridge service starts normally, but after sending an action goal (send_goal) a few times via ROS actions, the system throws an error. No other error messages or logs are observed beyond what has been described, and I cannot pinpoint the root cause.

Environment:

ROS Distro: ROS 2 Foxy
rosbridge Version: Likely the humble branch (latest from GitHub)

[bjsowa]

Foxy is EoL for almost 2 years now. The last version of rosbridge_suite released to this distro is 1.3.1 so you might try your luck with that instead of the latest commit.

If the issue still persists with the older version, it would help if you could get a backtrace

I'm currently using version 1.3.1. However, my ROS2 is the Foxy distribution. I’m not sure if this is causing the error
