It's wednesday night and I'm working on a client's project.
I'm making the app use S3 assets instead of assets compiled by me and on Heroku.
I notice that the production emails are wonky, specifically with the assets and links.
I grab letter_opener
and run development.
Suddenly, an error! I check out the trace and see that it's actually something wrong in letter_opener. I grab the trace line and google.
