    @bhudgeons is it possible you have an older/newer circe dependency elsewhere? These kinds of things are really annoying to track down, but I’m happy to make a featherbed release pointing to whatever the latest circe is.
    featherbed really needs some attention… I feel terrible about abandoning my finagle projects, but they just don’t get a lot of priority nowadays since I don’t use finagle at work.
    I also thought there were a couple of libs out there to supplant featherbed, but I don’t remember what I thought they were. Can’t immediately find one with good finagle/twitter-util integration. Hmm.

    @jeremyrsmith I wouldn't update to the 0.10.0 milestone, so there shouldn't be any need to update Featherbed immediately on the circe side (although a more recent Finagle would be nice).

    @travisbrown @jeremyrsmith thanks guys ... doing dependency spelunking now. Will investigate the issue, and I'll report.

    Dammit ... I'm using multiple libs that use circe, and it looks like one is actually using v0.9.0-M1, where Printer changed: https://github.com/circe/circe/compare/v0.9.0-M1...v0.9.1
    adding fields to the case class breaks the copy.
    [... right?]
    I'll track down which lib is the offender.
    thanks for your help

    @jeremyrsmith out of interest are you not using finagle because you've migrated to something else?
    jeremyrsmith
    @jeremyrsmith
    @dangerousben no, just because I changed jobs about 1.5y ago, and new company doesn’t use finagle (and I work on ML instead of web services/data eng. now, so even if they did I probably wouldn’t be working directly with it)

    @bhudgeons
    I found the problem. Featherbed-circe 0.3.2 uses circe 0.9.0-M2 and Printer did indeed change between then and 0.9.1. I'll get a PR in to upgrade circe to 0.9.1.

    @travisbrown
    @bhudgeons you can't update to 0.3.3?
    Brandon Hudgeons
    @bhudgeons
    There was no 0.3.3 tag, so I didn't think there was one.
    Does it upgrade to 0.9.0? That's what's in master, and I think that would work fine for me.
    Yep ... it does. Thanks @travisbrown!

    @jeremyrsmith no worries!

    hi is there an example of downloading a file from another webservice?
    may be the question can be phrased to are there any feather-bed decoders out of the box for decoding binary content?
    jeremyrsmith
    @jeremyrsmith
    @harrydevnull IIRC you can always get a Buf which gives you the bytes.
    harrydevnull
    @harrydevnull
    any code samples? @jeremyrsmith
    jeremyrsmith
    @jeremyrsmith
    hmm, not really. It looks like you’d want to make your own Decoder, i.e. for PDF:
    harrydevnull
    @harrydevnull
    :disappointed:
    jeremyrsmith
    @jeremyrsmith
    implicit val pdfDecoder: Decoder.Aux[Witness.`”application/pdf”`.T, PDF] = Decoder.of(“application/pdf”) {
  response => fnFromBufToPDF(response.content)
}
    sorry :(
    harrydevnull
    @harrydevnull
    that works :D
    jeremyrsmith
    @jeremyrsmith
    if you just want a Buf out it’s pretty trivial
    Decoder.of(“content/type”)(response => Validated.valid(_.content)) I think
    there should be an actual API for that, but there doesn’t seem to be.
    harrydevnull
    @harrydevnull
    implicit val streamDecoder: Decoder.Aux[Witness.`”application/octet-stream”`.T, PDF] = Decoder.of(“application/octet-stream”) {
  response => fnFromBufToPDF(response.content)
}
    i wanted something on that lines...
    jeremyrsmith
    @jeremyrsmith
    yeah, actually though the function has to return Validated[PDF]
    harrydevnull
    @harrydevnull
    implicit val streamDecoder: Decoder.Aux[Witness.`”application/octet-stream”`.T, Arrya[Byte] = Decoder.of(“application/octet-stream”) {
  response => fnFromBufToPDF(response.content)
}
    may be?
    jeremyrsmith
    @jeremyrsmith
    err ValidatedNel[Throwable, PDF]
    harrydevnull
    @harrydevnull
    cool I think I have enough to play with
    jeremyrsmith
    @jeremyrsmith
    yeah, in that case you’d want to just extract the byte array from the Buf, which there is an API for
    harrydevnull
    @harrydevnull
    thank you @jeremyrsmith
    jeremyrsmith
    @jeremyrsmith
    apologies for lack of any work on featherbed, keep meaning to merge #61 and then open up the maintainer chair, but can never find the time

    There was one another place I was stuck was making PUT request

    I have a (hopefully simple) featherbed question...
    i'm getting an error in my test..
    java.lang.NoSuchMethodError: io.circe.Printer.copy(ZZLjava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)Lio/circe/Printer;
    i'm not sure where that's coming from. the function being called is ...

    ```def createSession(client: Client): String = {
    val d = SSession("spark", "spark1")
    val headers = """{'Content-Type': 'application/json'}"""
    val req = client.post("/sessions").withContent(d, "application/json")

    Await.result {
  req.send[Response]() map {
    response => response.contentString
  }
}

    }```

    @jbelshaw-c7ks7s
    ok, some searching on here would indicate this is a dependency conflict issue?
    harrydevnull
    @harrydevnull
    @jbelshaw-c7ks7s yeah you have a Circe dependency conflict
    update to the latest version of feather bed and it seemed to work with Circe .9
