Hi everyone!

I’m working on the Markdown Previewer project. My code is working perfectly fine when I test it manually: headings, bold, and other elements are correctly converted in the preview.

However, the test runner keeps giving me this error:

“You should have a function named convertMarkdown that takes no parameters.”

I’ve double-checked everything:

The function name is exactly convertMarkdown.

It takes no parameters.

It correctly gets the value from #markdown-input

here is my code
