draftToHtml is not function

at the time of implementing the function I get the following error:

draftjs_to_html_1.default is not a function
TypeError: draftjs_to_html_1.default is not a function

Start by checking how draftjs-to-html is imported and exported in the reported WysiwygCustom usage, then compare that with the package's documented API. Reproduce the TypeError in the reported setup and confirm completion when converting Draft.js content to HTML no longer reports that default-export error.
