I have enabled a sensitive environment variable (lets call it MY_ENV_VAR) in My projects settings --> Build --> Environment variables.
I have a build, which I triggered via push. I ssh into the build and find that MY_ENV_VAR is being set. Great!
However, when someone else triggers the next build via PR, I notice it fails because the env var is not set. Rerunning and SSHing into the build I can confirm MY_ENV_VAR is NOT set.
config.yml, I do not set or edit MY_ENV_VAR. The only place where it is set is in the Build --> Environment variables menu in the Circle web app.
How can I enable this variable to be set for both builds triggered by me and by builds triggered by others?
