Spfx form customizer using dynamic form (react)

[DeathMaul23]

Hi, I tried using pnp dynamic forms Dynamic form documentation for saving lists which works fine, but saving doc sets I get this error

Any other methods for saving docsets than using
private _onSave = (listItemData: any, listItem?: IItem): void => { this.formSaved(); }

I used this repo as sample Conference-Sample

The latest release of PnP Controls adds support for doc sets creation.
From SPFx Core perspective - a developer is responsible for the logic of creating an item.
