core/group block attribute doesn't support cssClassName.

[feroz39]

Unlike other blocks, the core/group block attribute doesn't support cssClassName. Without this property, I can't properly style the markup.

... on CoreGroup {
  attributes {
    className
    cssClassName // I got error here
  }
}
... on CoreParagraph {
  attributes {
    className
    cssClassName
  }
}

The renderedHtml has the class but why the attributes don't? Please add this property to the CoreGroup.

Thanks @feroz39 for raising this issue.

I can replicate the issue and I will look into getting a fix for this issue.

@feroz39 I have created a PR #328 to fix the issue which will allow you to query cssClassName for the CoreGroup attributes node.
