iOS cloud build failure: "No project found at or above '/private/tmp/builds/_/[...]'"

Nel report non sono identificati file sorgente né test. Inizia riproducendo tns cloud build ios dalla root del progetto con le opzioni documentate per CLI e certificato, quindi segui il percorso del progetto mancante segnalato. Il lavoro è completato quando la cloud build individua il progetto e produce il .ipa previsto.

Environment

• CLI: 5.0.0-2018-10-05-12399 (Ubuntu 16.04 LTS)
• Cross-platform modules: 4.2.1
• Android Runtime: 4.2.0
• iOS Runtime: 4.2.0
• Plugin(s): package.json

Describe the bug
Local android builds succeed and install on an emulator with no issues. However, cloud build ios fails with the following error:

{after-prepare hooks and other normal stuff beforehand}

  ios Build Tooling revision 2018.08.08.1r
  Build Tooling Hostname administrators-mac-4.local
 App package not specified. Skipping unzip step.
  NativeScript CLI version 4.1.2
 Add platform ios with runtime version 4.2.0

Support for macOS 10.12 is deprecated and will be removed in one of the next releases of NativeScript. Please, upgrade to the latest macOS version.

Configures the current project to target the selected platform. 
### Options
    * --framework-path - Sets the path to a NativeScript runtime for the specified platform that you want to use instead of the default runtime. If --symlink is specified, <File Path> must point to directory in which the runtime is already extracted. If --symlink is not specified, <File Path> must point to a valid npm package.
    * --symlink - Creates a symlink to a NativeScript runtime for the specified platform that you want to use instead of the default runtime. If --frameworkPath is specified, creates a symlink to the specified directory. If --frameworkPath is not specified, creates a symlink to platform runtime installed with your current version of NativeScript.
    * --sdk - Sets the target Android SDK for the project.
    * --platform-template - Sets the platform template that will be used for the native application.
### Attributes
    * <API Level> is a valid Android API level. For example: 17, 19, MNC.
    * <File Path> is the complete path to a valid npm package or a directory that contains a NativeScript runtime for the selected platform.
    * <Platform Template> is a valid npm package, path to directory, .tgz or GitHub URL that contains a native Android or iOS template.
    * <Version> is any available version of the respective platform runtime published in npm.

Build failed.

Local android builds succeed with no issue.

To reproduce
Define following alias (split between multiple lines for legibility):

alias cloudbuild='echo -n "Enter password for Certificates.p12: " &&
read -s && echo &&
tns cloud build ios
    --accountId=1 --bundle --env.uglify --env.production --env.snapshot --release
    --certificate="/home/potassiumion/Downloads/Certificates.p12"
    --provision="/home/potassiumion/Downloads/Antem_Distribution.mobileprovision"
    --certificatePassword=$REPLY'

--provision and --certificate options link to valid files and --certificatePassword is correct

Run cloudbuild in root folder

I have tried using different nativescript versions as well, to no avail.

Expected behavior
Build should succeed and spit back an .ipa. Local android builds do work as expected.
