@dobey It does not seems to be working. I tried following 2 options
One:
Exec=webapp-container --allow-file-access-from-files --app-id="testionic.jitto" $@ www/index.html
Two:
Exec=webapp-container --local-content-can-access-remote-urls --app-id="testionic.jitto" $@ www/index.html
Both are not working. Same error ... 😰
