Microscope fails on heroku

[amralaaeldien]

when I start the app locally the app works just fine , however when I deploy it I get an "Application error" page saying
"An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details."
when I check "heroku logs" I get this
