Lists (ul and ol) are broken

Invariant Violation: convertToHTML: received block information without either a ReactElement or an object with start/end tags

This happens whenever there’s an ordered or unordered list. Adding the block types to the blockToHTML function has no effect. It still throws that error.

I just ran into this issue as well. This is what fixed it for me in case anyone else is stuck on the same problem (note the nestStart/nestEnd tags):

if (type === 'unordered-list-item') {
  return {
    start: '<li>',
    end: '</li>',
    nestStart: '<ul>',
    nestEnd: '</ul>',
  };
}
if (type === 'ordered-list-item') {
  return {
    start: '<li>',
    end: '</li>',
    nestStart: '<ol>',
    nestEnd: '</ol>',
  };
}

We are using your recommended example to me from awhile back:

const draftConverter = convertToHTML({
  blockToHTML: (block) => {
    if(block.type === 'header-two'){
      return {
        start: '<h2 class="title">',
        end: '</h2>'
      }
    }
    if(block.type === 'header-three'){
      return {
        start: '<h3 class="subtitle">',
        end: '</h3>'
      }
    }
    if (block.type === 'atomic') {
      return {
        start: '',
        end: ''
      }
    } else {
      return {
        start: '<p>',
        end: '</p>'
      }
    }
  },
  entityToHTML: (entity, originalText) => {
    const src = entity.data.src;
    if (entity.type === 'image') return `<div class="content-image">${originalText}<img src="${src}"/></div>`;
    else if (entity.type === '#mention') return parsers.games.hearthstone(entity);
    else return originalText;
  }
});
