Describe the bug

Hi!
When i try to read FormData with const formData = await readFormData(event) I receive this error:
[nuxt] [request error] [unhandled] [500] Error: Unexpected end of multipart data
It's come from Busboy

The problem appear when i set Content-Type on nuxt useFetch (also if i set lowercase content-type)

const headers = new Headers({
    'Content-Type': 'multipart/form-data; boundary=someBoundary',
  })
  const formData = new FormData()
  formData.append('test', 'string')

  const { data, error } = await useFetch('/api/file-upload', {
    method: 'POST',
    headers,
    body: formData,
  })

If i don't set Content-Type in local dev work perfect but on Netlify the problem appear again.
Did you know why?
Thank guys!
