Cannot Unmarshall Seq[String] Outside

[AlexWeinstein92]

I have a route that successfully uses complete after onSuccess to transform a Seq[GeneratedMessage] to Seq[String].

                onSuccess(
                  handler.func(...)
                ) { dataSeq =>
                  complete(
                    dataSeq.map(_.customPrint)
                  )
                }

However when I move the route to a function designed to replicate the route in its & other places, I get an IDE error saying Cannot resolve overloaded method 'complete'. I also get compiler error saying

found   : Seq[String]
[error]  required: akka.http.scaladsl.marshalling.ToResponseMarshallable

I'm not really sure what else to provide here... originally I was inside other Routes inside a trait which extends ErrorAccumulatingCirceSupport with StrictLogging. Now I am in a simple object. But I don't think expect of those things would have anything to do with this... the function that turns the GeneratedMessage into String is passed in now as a parameter to a def in the object I created, but all it does is call a custom helper function on GeneratedMessage that I wasn't able to call inside my def due to type erasure...

                onSuccess(
                  handlerFunc(...)
                ) { dataSeq =>
                  complete(
                    dataSeq.map(completeFunc)
                  )
                }

where completeFunc is a paramater passed in as {data => data.customPrint} and handlerFunc is also a parameter passed in as handler.func.

Essentially I built the function in the file it was originally in and the copy-pasted to a common object that I can use in other places. It was working fine within the original file. Now, it doesn't seem to want to transform my Seq[String] to toResponseMarshallable.
