Initialization fails in 3.8.0 beta

In version 3.8.0-beta, this code:

`        aladin = A.aladin('#aladin-lite-div');
`
triggers this error:

> Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'mode')


and Aladin Lite does not show.

`        aladin = A.aladin('#aladin-lite-div', {});
`
seems to be a workaround for now.
