    // won't get CSRF tokens and you'll get an exception at the other end of
    // the request which is a bit disconnected from the actual root cause.

// However, this is rare, and there are reasonable cases where this
    // construction occurs legitimately, and the simplest fix is to omit CSRF
    // tokens for these URIs in all cases. The error message you receive also
