Can't create destination service for a UI5 app for Build Work Zone

[alkozakiewicz1]

Full disclosure: Very experienced developer, but totally new to this product.

I am following the steps for Develop an App for SAP Build Work Zone, standard edition with Your Own Dev Tools.

I am on this page. When I perform the steps to deploy the application, I am getting the following error when it goes to create the destination service: Service broker error: Service broker destination-service-broker failed with: Service broker parameters are invalid: Destination name: contains invalid character.

What I believe is the relevant section of the mta.yaml file is as follows:

resources:

  - name: tutorial.myui5project-destination-service

    type: org.cloudfoundry.managed-service

    parameters:

      service: destination

      service-name: tutorial.myui5project-destination-service

      service-plan: lite

      config:

        HTML5Runtime_enabled: true

        version: 0.0.1

        init_data:

          instance:

            existing_destinations_policy: update

            destinations:

              - Name: ""

                Authentication: NoAuthentication

                ProxyType: Internet

                Type: HTTP

                URL: https://services.odata.org

                HTML5.DynamicDestination: true

                HTML5.ForwardAuthToken: true

This was all generated automatically by following the tutorial steps. A lot of Googling and searching the SAP KB has led me nowhere.  Any ideas?

as very experienced developer, did you ever read the error msg?

Why don't you give your destination a name? How would you expect to use a destination without a name?

#1, the code was generated automatically during the tutorial. 

#2 if, as I assume, I provide a name under destinations:, I get exactly the same error.

In Step 4 Create a new destination I can see that the destination is created manually. So it seems that the Instance destination in your mta.yaml was added by one of the yeoman generator steps. Have you tracked the steps with git commits? So you could find out. I would suggest that you remove everything starting at config. Maybe @nicoschoenteich can have a look here and do adjustments to the tutorial.

There was a recent change in the easy-ui5 project generator, more specifically the model subgenerator, as it can now add a destination and route (xs-app.json) for new data models automatically. We don't want this for this tutorial mission, as we add the route manually and create a manually added subaccount level destination. So when prompted to set up a route and destination as part of "yo easy-ui5 project model", say no. I will update the tutorial accordingly.

I will also update the easy-ui5 generator so that the destination name can't be empty 😅

Thanks for the answers (except one). If I am understanding correctly (no guarantee) there is now a problem with the tutorial here  in Step 5 as the route is now missing?
