Follow this: [Validation - JSON Forms](https://jsonforms.io/docs/validation#external-validation-errors)  
I got:  
Property ‘additionalErrors’ does not exist on type ‘IntrinsicAttributes & JsonFormsInitStateProps & JsonFormsReactProps’.

Can anyone help me with adding External Validation Errors for React? thanks!

HI @lfang001 and @MoHcmp,

The `additionalErrors` prop is pretty new and can only be used starting from ~~`v3.0.0-beta.2`~~ `3.0.0-beta.3` or later.

Edit: Fixed the version

Hi @sdirix @MoHcmp, thanks a lot for the reply! I updated to `v3.0.0-beta.2`, but i don’t know why i’m still getting the same error.

Hi @lfang001,

That was my mistake. I meant starting with `3.0.0-beta.3`. In any case I would always recommend using the latest version which is `3.0.0-rc.1`.
