title: could not find implicit value for evidence parameter of type io.finch.Decode.Json
body: <p>Has been working on this for a couple of days and still have no clue what's going on: 
  Got a finch web service, the build.sbt dependencies look like:</p>
  
  <pre><code>  "com.github.finagle" %% "finch-circe" % finchVersion changing(),
    "com.github.finagle" %% "finch-core" % finchVersion changing(),
    "com.github.finagle" %% "finch-jackson" % finchVersion changing(),
    "com.github.finagle" %% "finch-test" % finchVersion changing(),
    "com.twitter" %% "twitter-server" % "1.28.0",
  </code></pre>
  
  <p>The finch version is 0.14.0. 
  And the endpoint looks like:</p>
  
  <pre><code>  def makeService(statsReceiver: StatsReceiver): Service[Request, Response] = {
      //val getUserCounter = statsReceiver.counter("get_user_counter")
      (
        MyEndpoint.endpoint1()
          :+: SomeEndpoint.deleteEntity()
          :+: SomeEndpoint.createEntity()
          :+: SomeEndpoint.updateEntity()
        ) handle {
        case e: InvalidClientError =&gt; Unauthorized(e)
        case e: InvalidContextError =&gt; BadRequest(e)
        case e: RelevanceError =&gt; BadRequest(e)
        case e: Exception =&gt; InternalServerError(e)
      } toService
  </code></pre>
  
  <p>And I got the error message on the line of "toService" like:</p>
  
  <pre><code>[error] /workplace/relevance-service/src/main/scala/com/company/service/endpoint/serviceEndpoints.scala:39: An Endpoint you're trying to convert into a Finagle service is missing one or more encoders.
  [error]
  [error]   Make sure Exception is one of the following:
  [error]
  [error]   * A com.twitter.finagle.http.Response
  [error]   * A value of a type with an io.finch.Encode instance (with the corresponding content-type)
  [error]   * A coproduct made up of some combination of the above
  [error]
  </code></pre>
  
  <p>And I looked at:
  <a href="https://github.com/finagle/finch/blob/master/docs/src/main/tut/cookbook.md#fixing-the-toservice-compile-error" rel="noreferrer">https://github.com/finagle/finch/blob/master/docs/src/main/tut/cookbook.md#fixing-the-toservice-compile-error</a></p>
  
  <p>and tried the lines of:</p>
  
  <pre><code>import io.finch.circe._
  </code></pre>
  
  <p>And first of all, this io.finch.circe._ is not used in the code since it is grey in the IDE. And I still got the same build error. I'm totally lost here. Anyone can help me out what am I missing here? google/bing around did not get me anything very useful. </p>
  
  <p>Thanks. </p>
