TOSCA parser in XOS core will be updated, and many services unnecessarily import the old TOSCA parser (along with other unneeded imports) in a way that will break your service after this update is merged.
Remove the line import ToscaTemplate from the following 4 files:
- vBBU/xos/tosca/resources/mcordservice.py
- vBBU/xos/tosca/resources/vbbucomponent.py
- vPGWC/xos/tosca/resources/VPGWCService.py
- vPGWC/xos/tosca/resources/VPGWCComponent.py

You need to remove the existing docker image for the changes to take effect:
cd ~/service-profile/mcord/
make stop
make cleanup
sudo docker rm -f $(docker ps -aq)
