Application Cache Buster in HCP

As described in this help link - Application Cache Buster - UI Development Toolkit for HTML5 (SAPUI5) - SAP Library - App Cache Buster is also supported on HCP.

We have the following code which works well when deployed on Prem.








    "com.x.y": "./",

    "webapp": "./webapp"}'



When we deploy the same code on HCP, get the following error:

  1. Request URL:https://webapp- .
  2. Request Method:GET
  3. Status Code:404 Not Found


URL formation for on-prem:


URL formation for HCP:

https://webapp- .


Has anybody tried this out before and do we know of any solution ?

    Had raise this issue via SMP and got the following reply:

    the AppCacheBuster is not supported for HCP HTML5 applications out-of-the-box. The documentation is unfortunately misleading since it doesn't reflect the new HTML5 apps there and is based on the state for the  Java applications:

    For UI5 applications running on Java as well as for UI5 applications running on ABAP this file is generated automatically.

    You should either remove the option data-sap-ui-appCacheBuster="./" on the bootstrap script which disables the application cachebuster or you create this file manually - but for

    that scenario you have to take care that you handle the timestamps for the resources properly.

    Regarding the HTML5 apps roadmap - till now it is not planned to support it.

    Hi Parag,

    Warm Greetings. In HCP, this can be done by using Application Descriptor File (neo-app.json). Kindly refer the below links that has more detailed info.
