Failed unmarshalling using circe about scala-server-lambda HOT 3 CLOSED

Thanks for bringing this up. Basically what the issue is is that the content types are not passed through to akka, so everything is counted as a string. The generic marshallers and unmarshallers are strict and will only convert http bodies with a json content type. I will look into fixing this in a bit, I think I know how I can.

For now, if you change your (un)marshallers to this:

  implicit final def unmarshaller[A: Decoder]: FromEntityUnmarshaller[A] =
    Unmarshaller.stringUnmarshaller
     // .forContentTypes(`application/json`) // This is the line that causes the issue
      .flatMap { ctx => mat => json =>
        decode[A](json).fold(Future.failed, Future.successful)
      }

  implicit final def marshaller[A: Encoder]: ToEntityMarshaller[A] =
    Marshaller.withFixedContentType(`application/json`) { a =>
      HttpEntity(`application/json`, a.asJson.noSpaces)
    }

It should work. Note the commented line, which is what was causing this error.

I don't think this affects the http4s one, but I will check as well.

Notice this only happens when unmarshalling, custom marshallers work correctly.
Let me know if any help is needed 😄

Should be fixed now from baf3dda.
