    @ionos
    hello, I'm fairly inexperienced with both CouchDB and Sohva, apologies if my questions seem trivial
    Lucas Satabin
    @satabin
    hi
    Clemens Oertel
    @ionos
    I am playing around with CouchDB v2 and Sohva v2, and am experiencing an issue when trying to save views
    Lucas Satabin
    @satabin
    views are always hard to work with at the beginning :)
    Clemens Oertel
    @ionos
    design.saveView calls getDesignDoc, and the structure returned by CouchDB has 4 elements, but Sohva expects more fields to reconstruct a DesignDoc object
    so the deserialization fails
    Lucas Satabin
    @satabin
    hmmmm
    do you have the exact stacktrace?
    Clemens Oertel
    @ionos
    sure, one second
    Lucas Satabin
    @satabin
    I guess I see what the problem is, and it looks like a stupid bug in Sohva…

    if the design document already exists in Couch and was not created by Sohva, then some fields may not be present
    they actually are all optional
    Sohva should be prepared to have them missing
    can you please file a bug?
    with the stack trace
    Clemens Oertel
    @ionos
    when calling GET on http://localhost:5984/protoceratops/_design/test/, I get a dict with the keys _id, _rev, language and views only
    Lucas Satabin
    @satabin
    yes you’re right
    Clemens Oertel
    @ionos
    will do, thanks for the quick help
    Lucas Satabin
    @satabin
    np
    I will fix it today I think and publish a snapshot this evening (europe)
    is that ok for you?
    in the meantime you can work around the problem by editing the design in fauxton and add the missing fields 
    case class DesignDoc(
  _id: String,
  language: String,
  views: Map[String, ViewDoc],
  validate_doc_update: Option[String],
  updates: Map[String, String],
  filters: Map[String, String],
  shows: Map[String, String],
  lists: Map[String, String],
rewrites: Seq[RewriteRule])
    Clemens Oertel
    @ionos
    oh yes, sure, that's what I did, create them by hand
    Lucas Satabin
    @satabin
    ok super
    thanks for reporting
