Hello all! I’m trying to render a code block in a Portable Text Block, followed the instructions to add the serializer and still gives me the Unknown block type “code”, please...

import BlockContent from '@sanity/block-content-to-react'
const CodeRenderer = props => {
    console.log('Render code block: ', props)
    return BlockContent.defaultSerializers.types.block(props)
}

...

<BlockContent
   blocks={post._rawExcerpt}
   serializers={{
       types: {
           code: CodeRenderer
       }
   }}
/>
