Livewire 3 : @entangle is not recognized

Hello,

I have this code inside a tag.

x-data="{ color: @entangle('form.color') }"

And I get this error.

Error: Invalid or unexpected token Expression: "{ color: @entangle('form.color') }"

It's not the first time that I use @entangle and usually it works fine.

And the next error is color isn't defined.

What am I doing wrong ?

Thanks for your help.
