Error 404 when trying to access a full stack CAP application deployed in Cloud Foundry

Hello experts,

I have created a full stack CAP application and deployed it in Cloud Foundry. However when trying to access the app via HTML5 repository, I get a blank page and when I open the console, I see a bunch of 404 errors.

I have followed a youtube tutorial: https://www.youtube.com/watch?v=z10xke7yli4&list=PL54JdsBCvI0mPwzMkzlNnulw3NaxoWzks&index=23
The steps which I followed were exactly the same, still I am getting this issue.

Steps to reproduce:

1. Clone the github repository: https://github.com/developedbysom/cap-animal-adopt.git

2. Run npm install.

3. Run cds add hana --for production

4. Run cds add xsuaa --for production

5. Run cds add workzone (Since we are using managed approuter, this will also create xs-app.json in app/adopter)
6. Run npm install --prefix app/adopter/

7. Run cds add mta
8. Run mbt build -t gen --mtar mta.tar && cf deploy gen/mta.tar

I have added my xs-app.json,mta.yaml and manifest.json files as txt in the question.
Please look into this and guide me if I am doing anything wrong.

Thanks,

Regards,

Raihan

@raihan_siddiqui

Remove the leading slash from the following part of the manifest.json.

"uri": "/odata/v4/adopter/",

Alternatively, you can add the following task in the ui5-deploy.yaml. This task removes the leading slash during the build.

customTasks: - name: webide-extension-task-updateManifestJson afterTask: replaceVersion configuration: appFolder: webapp destDir: dist

@MioYasutakeThank you for your response. Eventually, after posting this, I came across the below tutorial from SAP

https://developers.sap.com/tutorials/deploy-to-cf..html

Here the steps mentioned helped me change the manifest.json as well as the mta.yaml file.

However, I do have one query. When the application is deployed, I see only 2 applications in my dev space, i.e. the service and the db-deployer.
Usually, we also have an approuter right from where we are able to access even the html5 app and accessing the html 5 app through cockpit leads to auth issue? What do we have to do do make our config that way? Also, is that the standard config which is followed?

Thanks,
