Remove duplicate messages

[LorenzHenk]

As seen in the screenshot, the same error messages are shown several times.

This happens in the error list on top of the form and under the element itself.

I haven't seen this problem on any other page (or with any other widget).

I have spent the last week with react-jsonschema-form and and rjsf-material-ui.
Therefore I can tell, that this is part of react-jsonschema-form validation as stated here.

If you don't want the Errorlist above the form, just add showErrorList={false} as a property to the component.

It's not about showing the errors, it's about filtering out duplicate error messages.

As you can see in the screenshot above, the message .colorPalette[0] should be string is shown 4 times in the error box - this does not make sense.

My bad, I misunderstood your description.
I would like to tackle this issue.

Thanks for the report! Anyway, this happens on react-jsonschema-form too.
So, @Benni2808 you also can send the proposal to react-jsonschema-form example repository.

But in addition to this, it's interesting to understand why when you use anyOf show duplicate messages.
