HOW TO REPRODUCE
================
- Don't need to login
- From Odoo front-end, go to Courses > Trees, Wood and Gardens >
Main Trees Categories
- You get the following client error:
Uncaught Promise > datetimeObj.getTime is not a function
HOW TO SOLVE:
============
Unlike standard JS equivalent, luxon datetime objects don't have a
getTime() function. Replace it by valueOf() function.
Also, remove calls to `DateTime.fromJSDate().formatting_fn()` by
luxon equivalent functions.
