Trying to migrate to rewrite, NPE

[nivekuil]

Running this:

(pack/docker {
             :tags        #{"latest"}
             :image-name  "..."
             :image-type  :docker
             :base-image  "ghcr.io/graalvm/jdk:ol8-java17-22"
             :basis       (b/create-basis {:aliases [:prod]})
             :jvm-opts    ["..."]}
)

returns:

Execution error (NullPointerException) at juxt.pack.jib/add-paths-entry (jib.clj:119).
Cannot invoke "Object.getClass()" because "target" is null

I added some logging to help debug:

should that :paths-layer ever be nil? There are other parts of the code getting NPEs as well.

This was caused by a :paths value in deps.edn pointing to a nonexisting directory. Worth handling?
