Kotless Hello World example fails deploying on AWS

[stefan-zh]

I am experiencing issues when trying to deploy the "Hello World" example for Kotless. I'm using the latest version of Kotless 0.1.7-beta-4.

BUILD SUCCESSFUL in 47s
6 actionable tasks: 2 executed, 4 up-to-date
22:47:36: Task execution finished 'deploy'.

I have 1 file, Functions.kt, containing the following:

package com.serverless.karti4ko

import io.kotless.dsl.lang.http.Get

@Get("/")
fun sayHello() = "Say Hello!"

My build.gradle.kts looks like this

import io.kotless.plugin.gradle.dsl.kotless

group = "com.serverless.karti4ko"
version = "1.0-SNAPSHOT"

plugins {
    kotlin("jvm") version "1.3.72" apply true
    id("io.kotless") version "0.1.7-beta-4" apply true
}

repositories {
    jcenter()
}

dependencies {
    implementation("io.kotless", "kotless-lang", "0.1.7-beta-4")
}

kotless {
    config {
        bucket = "my.serverless.bucket"

        terraform {
            profile = "my.kotless.user"
            region = "eu-west-1"
        }
    }
    webapp {
        lambda {
            kotless {
                packages = setOf("com.serverless.karti4ko")
            }
        }
    }
}

Expected events

1. Gradle deployment task should not be successful when the deployment is unsuccessful.
2. The "Hello World" example as given on the README for Kotless should deploy successfully.

Are you building on Windows? If that's the case, please check that new line feeds are LF. It is a well-known bug that should be fixed.

Hey @TanVD I'm building on Windows. I converted all line feeds to LF, but I still got the same error above.

I have the same issue. How can I deploy the same Kotless app into different AWS environments (prod/dev)?

[hamadycisse]

I was able to solve the issue by using a prefix

kotless {
    config {
        prefix = System.getenv("DEPLOYMENT_PREFIX") ?: "dev"
    }
}
