Format validation failed - Route references unknown destination

Hi All,

I am getting below error while trying to start the web module of SAP HANA XSA MTA application.

I have maintained destinations using group: destinations property. Is there anything that I am missing here?

Can you show your mta.yaml and xs-app.json files.

mta.txt

xs-app.txt

Thank you for your response. I am attaching the MTA.YAML and XS-APP.JSON files.

Rename in your mta.yaml the the name of the provided service to something else than "js" (which is the module name for the nodejs module). For instance call it "js-service". Also adjust the requires section of the web module with the new name.

...

 - name: js
   type: nodejs
   path: js
   provides:
     - name: js-service
       properties:
         url: "${default-url}"
   requires:
     - name: xsprototype-uaa
     - name: db
     - name: hdi-container
       properties:
         TARGET_CONTAINER: ~{hdi-container-name}


 - name: web
   type: html5
   path: web
   requires:
     - name: xsprototype-uaa
     - name: js-service
       group: destinations
       properties:
         name: backend-service
         url: ~{url}
         forwardAuthToken: true

Thanks Florian. That worked.

[m_krishnapillai]

Got it working. MTA.yaml file had an incorrect required service entry.
