I am seing errors deploying to Heroku – even for builds that worked 1 week ago
"heroku config:set BUILD_NUMBER=$CIRCLE_BUILD_NUM BRANCH=$CIRCLE_BRANCH ENV=staging --app MyApp
Setting BUILD_NUMBER, BRANCH, ENV and restarting ⬢ MyApp… !
▸ “port” option should be >= 0 and < 65536: null
the build was canceled"
this config works fine if I run it locally and it was working through Circle as of 1 week ago
