Only looking for "---" is insufficient to determine the multipart boundary, as the string can occur within JSON objects.
As specified in https://datatracker.ietf.org/doc/html/rfc2046#section-5.1, the delimiter should be on a separate line, which means we can recognize it by the newline control characters that won't occur inside JSON objects.
