AuthorizationError: The provided request must include a 'scope' input parameter.

I tried your example and got the following error after hitting the "login with onedrive" button:
AuthorizationError: The provided request must include a 'scope' input parameter.
MicrosoftOneDriveStrategy.OAuth2Strategy.authenticate (c:\Users\xxxxxx\Documents\VS Code\passport-onedrive-master\examples\login\node_modules\passport-onedrive\node_modules\passport-oauth2\lib\strategy.js:136:25)

You need to specify a scope in the options parameter:

app.get(
  "/auth/onedrive",
  passport.authenticate("onedrive", { scope: "Files.ReadWrite.All" })
);
