Ask questionsclient not receiving response after unpiping busboy from from limit event

after unpiping busboy from the limit event handler no response is received by the client, not unpiping busboy works fine but requires the remainder of the upload to be sent to the server.

unpiping and returning a response from a custom event in the same way works fine

//Don't work
file.once('limit', () => {
  return res.status(413).json({
    file: filename,
    status: 413,
    message: 'file too large'

// Work fine
filesig.on('signature', signature => {
  if (!signature.mimetype.includes(fileinfo.type)) {
    return res.status(415).json({
      file: filename,
      status: 415,
      message: 'invaild filetype'

I'm not sure what you mean by 'custom event', but did you try adding req.resume() after unpiping?
