Server side validator, what's wrong?

You can see on my picture that i’ve tried with insertedid or idform.
idform is placed at the top of the repeat:

and insertedid before the validate and insert

Turns to:

(BTW don’t know why the set value insertedid turns to be after the insert)

100% sure

Found this topic, so I guess it’s not possible have a validate step on a repeat:
www.community.wappler.io/t/how-to-add-a-server-side-validate-step-on-a-repeat-element/18431

And the workaround:

I’ll wait to the team confirms that it’s impossible to make it work, and then I’ll create a FR for having a validate on repeat.
