My local simulation not loading correctly as a rosject

[dorteel]

Hi there!
I’m trying to make a simulation that both me and my students use regularly into a rosject. However, when I try to run it, I get an an error, and the simulation would not start.
I’ve used my simulation in several different machines without a problem, so not sure how to handle this error.

Service call failed: transport error completing service call: unable to receive data from sender, check sender's logs for details

Simulation repo: GitHub - Dorteel/locobot_simulation
Rosject link: https://app.theconstruct.ai/l/64f1e510/

Launch file:
roslaunch locobot_simulation simulation.launch
I attached a screenshot of how it looks on my local machine.
Any help would be appreciated!

GAZEBO_MASTER_URI

This could be related to ROS/Gazebo variables like this one, since it seems to be a communication problem.

Generally speaking, this specific variable needs to be set automatically on our platform; things might not work if they are set to custom values.

One way to audit these variables would be to check the values for a rosject created out of the box on the platform vs this one you are trying to create from a repository.

Thanks for the reply! I tried to check these environment variables, and to enforce some of them, but had no luck so far. I’ll update the post if I find something.
