I knew that posting this problem would help me find the fix.

Posting led me to this thread with this answer by @Mark:

I realized almost instantly that my `config/runtime.exs` does have an error. Endpoints are configured by the web context, not the app context so I changed to configuring `ShrimpWeb.Endpoint` instead of `Shrimp.Endpoint` and it fixed the issue.

I’m sure that Chris and Mark are probably working on mistake-proofing these deploys. I’m happy to help if this is desired. I’m good at breaking things. 😉
