Describe the Bug

When a Collection has a block field with some available blocks and one of these blocks has an additional blocks field It's not possible to generate a migration for this field.

We have a page collection with some Blocks. The blocks field looks like this:

{
      name: 'content',
      label: 'Content',
      type: 'blocks',
      minRows: 0,
      localized: true,
      blocks: [
        RichTextBlock,
        ImageBlock,
        TextImageBlock,
        LocalVideoBlock,
        RemoteVideoBlock,
        CTABlock,
        StructuredDataBlock,
        HighlightBoxBlock,
        AccordionBlock,
      ],
    },

The AccordionBlock now should allow for multiple accordion items where each one has a title and can have additional content elements inside.

The base fields for the accordionBlock look like this (First without the block in block feature):

fields: [
    {
      name: 'panels',
      label: 'Accordion Panels',
      type: 'array',
      fields: [{ name: 'title', label: 'Panel Title', type: 'text' }],
    },
  ],

This works. However when we add a blocks field inside the accordion fields we get different error messages:

1. version (It should work like this?)

fields: [
        { name: 'title', label: 'Panel Title', type: 'text' },
        {
          name: 'content',
          label: 'Content',
          type: 'blocks',
          localized: true,
          minRows: 0,
          blocks: [RichTextBlock, ImageBlock],
        },
      ],

yields [08:27:02] ERROR (payload): Error: cannot connect to Postgres. Details: Cannot read properties of undefined (reading 'Symbol(drizzle:Name)') when running payload migrate:create

Strange error which has nothing to do with the connection but seems like a serious issue in Drizzle?

2. version (differentiate blocks db table)

fields: [
        { name: 'title', label: 'Panel Title', type: 'text' },
        {
          name: 'content',
          label: 'Content',
          type: 'blocks',
          localized: true,
          dbName: 'accordion_item_content',
          minRows: 0,
          blocks: [RichTextBlock, ImageBlock],
        },
      ],

yields [08:28:22] ERROR (payload): There were 1 errors validating your Payload config [08:28:22] ERROR (payload): 1: Collection "pages" > Field "content" > "value" does not match any of the allowed type when running payload migrate:create.

If i remove the AccordionBlock from the pages collection it works again. So unsure which value is checked here.

If i remove the localized: true from the field i the yielded error is:

InvalidConfiguration: The table pages has multiple blocks with slug richText, but the schemas do not match. One is localized, but another is not. Block schemas of the same name must match exactly.

also with a different dbName for the accordion item.

I think it would work if I would create dedicated accordion_item_rich_text blocks but I would like to not go that route if possible.

Any hints on where to go from here would be very good!
