Error when adding cron (frontend)

[TBG-FR]

When trying to add a cron through the frontend, the console shows the following error (but the cron is added)

vue.esm.js:1897 TypeError: undefined is not iterable (cannot read property Symbol(Symbol.iterator))

I'm using the "latest version" (= git clone + Dockerfile)
