That's a rude awakening but an expected one. It's very easy to write an elegant piece of code in scripting language only to find that some of dependencies who work magic are pretty messy to deploy.

You can usually count on having native libraries for a given activity for Java, so you can just use a JVM-based language (does Lambda support that? I bet it does.)

Further down the article she mentions that she solved the dependency by "I ended up rewriting the Lambda in Java", noting that the use-case doesn't care about the known JVM warmup times.

The POM packaging and jar based deployment seemed to make the dependencies work.

You can surely write lambda functions in Clojure (or Clojurescript)! Clj on JVM on Lambda is almost a nonstarter for some tasks. A 10+ second cold start warm-up time isn't viable for a lot of use cases.
