Error record is undefined when use toggleCustomInlineStyle on an entity (RawDraftEntity)

[lafonju]

Hey,
I would like to know if it is possible to use the toggleCustomInlineStyle method on an entity (RawDraftEntity) ?
For example, I have an html code with custom tags
<var data-name="$test">

I use htmlToDraft method for convert this code with a customChunkRenderer

private static customChunkRenderer(nodeName: string, node: HTMLElement): RawDraftEntity | undefined {
        let draftEntity: RawDraftEntity | undefined;
        if (nodeName === 'var') {
            const data = {
                name: node.dataset.name
            };
            draftEntity = {
                type: VariableType,
                mutability: 'IMMUTABLE',
                data: data
            };
        }
        return draftEntity;
    }

When I want to change the text size of my item, with the toggleCustomInlineStyle method, I get the following error message

TypeError: record is undefined
removeStyle
.../node_modules/draft-js/lib/CharacterMetadata.js:56

  53 | };
  54 | 
  55 | CharacterMetadata.removeStyle = function removeStyle(record, style) {
> 56 |   var withoutStyle = record.set('style', record.getStyle().remove(style));
     | ^  57 |   return CharacterMetadata.create(withoutStyle);
  58 | };
  59 | 

Then I want to retrieve the HTML code with the style applied to my item, with draftToHtml and my method customEntityTransform

private static customEntityTransform(...args): any {
        const entity = args[0] as RawDraftEntity;
        let value: string | undefined;
        if (entity.type === VariableType) {
            value = '<var data-name="' + entity.data.name + '">';
        }

        return value;
    }

Thank you very much
