I had some waitQueue size limit exceeded issues in the past with my http4s-blaze-client@0.21.0-M6. As per the recommendation I am trying to upgrade my http4s version from 0.21.0-M6 to 0.21.33. Now I am facing the below compilation error in the code:
Symbol 'type cats.package.MonadThrow' is missing from the classpath.
This symbol is required by 'value org.http4s.Media.F'.
Make sure that type MonadThrow is in your classpath and check for conflicting dependencies with -Ylog-classpath.
A full rebuild may help if 'Media.class' was compiled against an incompatible version of cats.package.
could not find implicit value for parameter F: cats.MonadThrow[[_]F[_]]
parsedRequest <- authedReq.req.as[CreateScheduleRequest]
I referred to https://http4s.org/versions.html and it looks like I am using all the compatible versions. The only dependency I changed was of the http4s. Rest of the dependencies were unchanged and were working fine with http4s@0,21,0-M6. I am new to http4s and cats-effect. Could someone please suggest what can be done to fix the above issue?
Below is the summary of my dependencies:
val mqtt = "org.eclipse.paho" % "org.eclipse.paho.client.mqttv3" % "1.2.2"
val doobie = "org.tpolecat" %% "doobie-core" % "0.8.8"
val doobieJDBC = "org.tpolecat" %% "doobie-postgres" % "0.8.8"
val doobieCP = "org.tpolecat" %% "doobie-hikari" % "0.8.8"
val flyway = "org.flywaydb" % "flyway-core" % "6.2.2"
//common
val http4sDsl = "org.http4s" %% "http4s-dsl" % "0.21.33" //previously "0.21.0-M6"
val http4sServer = "org.http4s" %% "http4s-blaze-server" % "0.21.33" //previously "0.21.0-M6"
val http4sClient = "org.http4s" %% "http4s-blaze-client" % "0.21.33" //previously "0.21.0-M6"
val http4sCirce = "org.http4s" %% "http4s-circe" % "0.21.33" //previously "0.21.0-M6"
val chimney = "io.scalaland" %% "chimney" % "0.4.1"
val catsEffect = "org.typelevel" %% "cats-effect" % "2.1.0"
val mouse = "org.typelevel" %% "mouse" % "0.24"
val circeParser = "io.circe" %% "circe-parser" % "0.13.0"
val circeGeneric = "io.circe" %% "circe-generic" % "0.13.0"
val circeGenExt = "io.circe" %% "circe-generic-extras" % "0.13.0"
val config = "com.typesafe" % "config" % "1.4.0"
val logback = "ch.qos.logback" % "logback-classic" % "1.2.3"
//test
val moquette = "io.moquette" % "moquette-broker" % "0.11"
val doobieH2 = "org.tpolecat" %% "doobie-h2" % "0.8.8"
val scalaTest = "org.scalatest" %% "scalatest" % "3.2.0-M2"
scalaVersion = "2.13.1"
Below is the http4s route class that is giving the compilation error:
import java.time.LocalDateTime
import cats.effect._
import cats.implicits._
import io.circe.generic.auto._
import org.http4s._
import org.http4s.dsl._
class ScheduleRoute[F[_]: Effect] extends Http4sDsl[F] with HttpMarshalling with HttpResponseHandler[F] {
final def serve(service: ScheduleServiceAlgebra[F]): AuthedService[User, F] = AuthedService{
case authedReq @ POST -> Root / "buildings" / InstallationUuidVar(installationUuid) / "entries" as user =>
val io = for {
parsedRequest <- authedReq.req.as[CreateScheduleRequest]
validRequest <- parsedRequest.validate
result <- service.createSchedule(installationUuid, validRequest, user)
now <- Sync[F].delay(LocalDateTime.now(java.time.ZoneId.of("UTC")))
} yield result.withNextOccurrenceTime(now)
io.result
}
}
P.S. I ran sbt evicted command and see the following. Does it mean I need to update some of the dependencies?
