CAP MTA Deployment with launchpad service

[former_member743968]

Tutorials: https://developers.sap.com/tutorials/btp-app-launchpad-service.html
--------------------------

On step 13, MTA re-deployment - I am receiving an error that my Resource object is null. Any ideas on how to troubleshoot?

Error resolving merged descriptor properties and parameters: Cannot invoke "org.cloudfoundry.multiapps.mta.model.Resource.getProperties()" because "resource" is null 
Process failed.

Hi austinkloske ,

It might be a formatting issue with respect to white space, could you share your mta.yml file?

Ok! Solution found, this is an issue I havent seen before. Here are the steps to solve it;

1. mta.yaml

Update the supported-platforms: [] to supported-platforms: [CF] inside the securitychecks module

2. Update securitychecks_ui_deployer -> package.json to the following so that it works with the latest nodejs versions, might not be applicable to you

{
 "name": "approuterUIDeployer",
                "dependencies": {
                	"@sap/html5-app-deployer": "4.1.0"
                },
                "scripts": {
                "start": "node node_modules/@sap/html5-app-deployer/index.js"
                }
}

I’ve also created a package.json that you can run cli commands. You can drop this into the root of your project folder;

{
    "name": "securitychecks-project",
    "version": "0.0.1",
    "description": "Build and deployment scripts",
    "scripts": {
        "clean": "rimraf resources mta_archives mta-op* Makefile_*",
        "build": "rimraf resources mta_archives && mbt build --mtar archive",
        "deploy": "cf deploy mta_archives/archive.mtar --retries 1",
        "undeploy": "cf undeploy securitychecks --delete-services --delete-service-keys"
    },
    "devDependencies": {
        "mbt": "^1.0.15",
        "rimraf": "3.0.0"
    }
}

So you can now run the following commands;

npm i
npm run build
npm run deploy
npm run undeploy
