Attachment with LF in body is being replaced to CR LF

## Describe the bug
I am sending an text attachment with LF in the api but the attachment is received with CR LF

this is an issue because my client is comparing hashes and becuase of that the hashes are not the same

## To Reproduce

1. Convert a file with LF to base64
2. Send it using the api
3. The attachment wiill be with CR LF instead of LF

## Expected behaviour

The attachment should be exactly how sent it

## Environment details

- OS: sending http with Windows , node js with axios
- Version 3.3.4
