To Reproduce

• I am attaching my geojson file and sys param file.
• The system parameter was created using the UO CLI
• Command used to run TN:

bundle exec uo ghe_size -y .\ghe_project_3\sys_param.json -s .\ghe_project_3\baseline_scenario.csv -f .\ghe_project_3\balanced_load.json

Expected behavior

TN sizes GHE

Desktop (please complete the following information):

• Windows
  balanced_load.json
  sys_param.json

I manually added the "is_ghe_start_loop": true property to the junction connected to the GHE, and got past this error.

This property is not added automatically using the UO internal UI

Thanks. Does this need to be documented on the UO repo?

Yes, added a feature request urbanopt/urbanopt-cli#491
