You also have to shade shapeless inside its own JAR, in addition to pureconfig:

assemblyShadeRules in assembly := Seq(
  ShadeRule.rename("shapeless.**" -> "shadeshapless.@1")
    .inLibrary("com.chuusai" % "shapeless_2.11" % "2.3.2")
    .inLibrary("com.github.pureconfig" %% "pureconfig" % "0.7.0")
    .inProject
)

Make sure to add the correct shapeless version.
