Just a quick note this time. While working on my Phoenix 1.3 based project, I had a route that was failing and gave me an error about the fallback controller not having a matching clause. Similar to (formatted excerpt): ** (exit) an exception was raised: ** (FunctionClauseError) no function clause matching in MyProj.Web.FallbackController.call/2 My route looked to be setup correctly and I couldn’t figure out why I was hitting the fallback controller at all.
