I created a block to display a custom data I fetch from the DB, I don't need customization (fields) for this blocks. But in the editor doesn't render de template unless there is a field and the field is filled.
I would also like the block to render even if there are no custom fields. It does not make any sense to tell the user, "Click the Edit icon in the block toolbar to enter content" if there are no fields to fill out.
My block does technically have a "field" in the list of Fields in Edit Field Group, but it is just Custom HTML that explains the block has no settings. It still renders in the editor with the "Click the Edit icon" message.
