Microsoft Graph, Node.js, Failed sign on using acquireTokenByUsernamePassword

Question

I would like support troubleshooting a sign on error. For background, I am building an application that accesses data stored on SharePoint. I am experiencing an issue generating the necessary auth token using Node.js. As I am in development, I want acquire a token using Username and Password.

I repurposed the code here: https://learn.microsoft.com/en-us/azure/active-directory/develop/scenario-desktop-acquire-token-username-password?tabs=nodejs

Using Python, I was successful. However using Node.js I received the below error.

Note: I am certain that the username and password were the same in both Python and Node.
