failed to create auth request

Error message

failed to create auth request: %w

What it means

Returned when http.NewRequest fails while building the POST to Ring's OAuth token endpoint. In practice this happens only if the OAuth URL is malformed (unparseable URL), since the body is a valid bytes.Reader.

Solutions

1. Check the wrapped error (url.Parse error) for the malformed URL detail
2. Verify the OAuth endpoint URL configuration (no empty or garbled value)
3. Ensure any base-URL override is a valid absolute http(s) URL

Example fix

// before
cfg.OAuthURL = "" // yields unparsable request URL
// after
cfg.OAuthURL = "https://oauth.ring.com/oauth/token"

if u, err := url.Parse(oauthURL); err != nil || u.Scheme == "" || u.Host == "" {
    return fmt.Errorf("invalid oauth url %q", oauthURL)
}

When it happens

Trigger: oauthURL is empty, malformed, or contains invalid characters so http.NewRequest cannot parse it.

Common situations: Misconfigured base URL / OAuth endpoint override; empty config value substituted for the OAuth URL; environment-specific URL rewrites with bad characters.
