[3.8.0-rc.1] blocks and layout field issues within object field

[afbora]

Getting following error when using blocks and layout fields within object field

Cannot read properties of null (reading 'length')

fields:      
  person:
    label: Person
    type: object
    fields:
      blocks:
        type: blocks
      layout:
        type: layout

Additional context

Seems to happen when the field is named blocks and layout, works if you give it another name.

Issue summary

The issue is setting field value as null and coming from following line: https://github.com/getkirby/kirby/blob/3.8.0-rc.1/panel/src/components/Forms/Field/ObjectField.vue#L99

Possible solution

It works when field.value or empty string is returned instead of null. However, I think that the value prop of all fields should return the type it supports in order for it to work more stable in the future.

@bastianallgeier Unfortunately no.

@afbora it was completely unrelated, but this should fix it: https://github.com/getkirby/kirby/pull/4700
