Passwordless/User Authentication Help

I know this is a long shot but I was hoping someone might be able to help me with passwordless authentication on the server side. I know my client side is working just fine (i’ve checked req.body and it contains the email address), but I have no idea what is going wrong. No error is thrown, yet the email is never sent! This bug is driving me crazy and I have no idea what the issue is.

If anyone is willing to take a look I would be forever thankful.

Check the outlook account you are sending from - when I was getting started I had to deal with some small account restrictions and verification before they would reliably send.
