akka-http-rest's Issues

503 Application error.

I was just trying to go through the code and clicked on the link for live example. It is giving 503 "Application Error". I am facing the same issue on my akka http app on Heroku. Do you know what it might be? Logs are not showing much info on it.

How to fix Slick Exception of single AutoInc column returned on INSERT

I tried to implement the akka-http rest example provided at
https://github.com/ArchDev/akka-http-rest
but I'm stuck with the

    slick.SlickException: This DBMS allows only a single column to be returned from an INSERT, and that column must be an AutoInc column.
    at slick.jdbc.JdbcStatementBuilderComponent$JdbcCompiledInsert.buildReturnColumns(JdbcStatementBuilderComponent.scala:67)

Here is the Scala Code:
Signup API:

path("signUp") {
    pathEndOrSingleSlash {
      post {
        entity(as[UsernamePasswordEmail]) { userEntity =>
          complete(Created -> signUp(userEntity.username, userEntity.email, userEntity.password))
        }
      }
    }
  }

AuthService.scala

def signUp(login: String, email: String, password: String): Future[AuthToken] =
    authDataStorage
      .saveAuthData(AuthData(UUID.randomUUID().toString, login, email, password.sha256.hex))
      .map(authData => encodeToken(authData.id))

AuthDataStorage.scala

...
override def saveAuthData(authData: AuthData): Future[AuthData] =
    db.run((auth returning auth).insertOrUpdate(authData)).map(_ => authData)
...

Since I'm new to Scala and Slick, can anyway provide the information why this exception is occurring even though I've defined O.AutoInc in Model. I'm using MySQL RDBMS
