Multer breaks res.send

[TheSainEyereg]

When client provides bad Content-Length header or does not provide it at all, multer usually returns an error code 400, but in case when this header is missing, you can simply add a line to tell the user that he needs a content length header:

But when Content-Length has a bad value, and you try to send information about this problem back to the user using res.send (or res.json), it doesn't send anything, only the HTTP 400 code:
