[SOLVED] Error while deploying SAP Fiori and CAPM application in SAP BTP Trial Account

I created a basic SAP CAP/Fiori application using BAS of SAP BTP, with HANA DB Instance created. It's working fine when I run it locally. However, during deployment to SAP BTP Trial Account, I encountered the issue/error below.

After deployment was completed with errors, the SAP CAP Service is working fine, only the SAP Fiori which is not working since an error was encountered during deployment.

Error encountered during deployment

Error starting application "Bookshop2": Some instances have crashed. Check the logs of your application for more information.
Download the application logs via the dmol command and check them for more information.
A step of the process has failed. Retrying it may solve the issue.
Proceeding with automatic retry... (3 of 3 attempts left)

Content of dmol(Logs)

Inside dmol, an error Cannot open: No space left on device was encountered.

Steps for deployment

Cds add hana –for production
Cds add xsuaa –for production
Cds add mta (Optional in case you don’t have it yet.)
Cds add approuter –for production
It will generate xs-app and default-env.json inside /app folder. 
Npm install

Cds build –production
Mbt build -t gen –mtar mta.tar

cf login
cf deploy gen/mta.tar

Update: Solution to the Deployment Issue.

You need to change the disk-quota and memory of your Fiori/SAUI5 app from 256M to at least 1024MB.
