‘class rmf_traffic::agv::Graph::Lane’ has no member named ‘properties’

Hi,
When i am colon build the rmf_ws, it has failed because of the error: ‘class rmf_traffic::agv::Graph::Lane’ has no member named ‘properties’.

One of my teammate have found dual boot as one of the solution to the problem, but is there other way to solve this? Or is this a problem with my system specification?
My ubuntu 20.04 LTS was run on Vmware Workstation Player 16

The Lane::Properties member is available on the latest merge: open-rmf/rmf_traffic#44. You might need to git pull (or vcs pull) to update all your local rmf repo.
Or potentially, you might have installed the rmf debian binaries (e.g. ros-foxy-rmf-*) locally. This might cause conflict.

Thanks for helping, it worked after I remove the ros-foxy-rmf-demos-gz and retry the whole process with a new wget/git clone.
