1. Prerequisites executed as described in section: https://cap.cloud.sap/docs/guides/deployment/to-cf#prerequisites ; sample code used from https://github.com/capire/bookshop.git
2. Mandatory steps (1.-5.) executed as described in section 'Prepare for Production': https://cap.cloud.sap/docs/guides/deployment/to-cf#prepare-for-production
3. In 'Build and Deploy' 'cds up' command failed with the following output (entire output in [1])

This log entry indicates that the package.json file does not have a script with "build" name:

npm error Missing script: "build"

for example:

  "scripts": {

    "start": "cds-serve",

    "watch-bookshop_ui": "cds watch --open bookshopui/index.html?sap-ui-xx-viewCache=false --livereload false",

    "undeploy": "cf undeploy mybookshop --delete-services --delete-service-keys --delete-service-brokers",

    "build": "rimraf resources mta_archives && mbt build --mtar archive",

    "deploy": "cf deploy mta_archives/archive.mtar --retries 1"

  },

Could you check the scripts section? Maybe the build script was renamed.

Hi AntalP,

thank you for your comments.

The sample/repo  I'm using is public pls check the script section: https://github.com/capire/bookshop/blob/main/package.json#L19

If there is anything you know I should/could fix pls let me know and I try it out.

Best regards, Jens
