Quotes run when rendering occurs

Hello, after changing the heading and parameters of prosemirror from nodes to marks, I saw a blockquote that said no node type or group ‘paragraph’ found in content expression’ (paragraph | heading)+, and when it was first executed, I corrected the content part to inline*, and the backquote came out If I erase the content, I can’t enter it at all, and if I put an empty array in the toDOM part, it says cannot read properties of undefined (reading ‘indexOf’), is there a way to make blockquote come out without running when it first runs?

blockquote: {
    content: '(paragraph|heading)+',
    group: 'block',
    defining: true,
    parseDOM: [{tag: 'blockquote'}],
    toDOM() {
      return blockquoteDOM
