Oauth authentication fails with 404 error

[DIPAD-Fran-Bryden]

When authenticating via credentials_user_oauth2, the authentication dance ends in a 404 error rather than the expected code to pass back to RStudio console.

Example:

scope <- c("https://www.googleapis.com/auth/cloud-platform")

token <- gargle::credentials_user_oauth2(
  scopes = scope
)

This prompts the expected authentication process, but the final screen shows

Instead of the authentication code.

If I execute the code above and click through the screens, I end at this screen, which is success:

So there has to be something more going on in your case.

I don't actually understand how this is connected at all with GitHub or GitHub Pages.
