Tapir - Method too large

Question

Im defining endpoints using tapir however i get the following compilation error.

[info] Compiling 3 Scala sources to /endpoints/target/scala-2.13/classes ... [error] Error while emitting/endpoints/Session$ [error] Method too large: endpoints/Session$. ()V [error] one error found [error] (endpoints / Compile / compileIncremental) Compilation failed [error] Total time: 26 s, completed 12-Mar-2020 15:29:54

 val manualReviewEndpoint: Endpoint[(SessionModel.AuthToken, SessionModel.ManualReview.ManualReviewRequest), ErrorsModel.FailureResponse, SessionModel.ManualReview.ManualReviewResponse, Nothing] = endpoint
    .tag("Sessions")
    .description("Triggers manual review for sessions within date range")
    .post
    .in(auth.bearer)
    .in("sessions" / "trigger-review")
    .in(jsonBody[SessionModel.ManualReview.ManualReviewRequest])
    .out(jsonBody[SessionModel.ManualReview.ManualReviewResponse])
    .errorOut(oneOf(
      statusMapping(StatusCode.BadRequest, jsonBody[ErrorsModel.FailureResponse400]),
      statusMapping(StatusCode.Unauthorized, jsonBody[ErrorsModel.FailureResponse401]),
      statusMapping(StatusCode.NotFound, jsonBody[ErrorsModel.FailureResponse404]),
      statusMapping(StatusCode.UnprocessableEntity, jsonBody[ErrorsModel.FailureResponse422]),
      statusMapping(StatusCode.FailedDependency, jsonBody[ErrorsModel.FailureResponse424]),
      statusMapping(StatusCode.InternalServerError, jsonBody[ErrorsModel.FailureResponse500]),
    ))

Answer 1

It looks like because i had so many endpoints with many statusMappings that it was causing the constructor to become too large.

I fixed this issue by putting manualReviewEndpoint into its own object.
