2. Run npm run test

Additional information

[vallq]

Updating the Pipfile to add fastapi = "~=0.63.0" to [packages] or pipenv install 'fastapi~=0.63.0' and making sure that port 8000 is not in use (lsof -i TCP:8000 | grep LISTEN) allows the e2e to run correctly. but I'm still not sure why it is this way because the dependency of api-server does not need to change.

Pipfile

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
fastapi = "~=0.63.0"

[dev-packages]
black = "==20.8b1"
isort = "~=5.8"
pylint = "~=2.7"
coverage = "~=5.5"
# api-server
api-server = {editable = true, path = "./packages/api-server"}
requests = "~=2.25"
# reporting-server
reporting-server = {editable = true, path = "./packages/reporting-server"}
# ros-translator
ros-translator = {editable = true, path = "./packages/ros-translator"}

[requires]
python_version = "3.8"

Adding the fastapi package to [dev-packages] will cause the confict error to appear

pkg_resources.ContextualVersionConflict: (fastapi 0.65.2 (/home/chawin/rmf-web/.venv/lib/python3.8/site-packages), Requirement.parse('fastapi~=0.63.0'), {'api-server'}

Older versions of fastapi had a security vulnerability so it needs to be updated, try clearing the .venv dir and running bootstrap again.

Solved by clearing .venv
