Failed to build OAuth URL

Error message

Failed to build OAuth URL

What it means

get_auth_url unwraps get_auth_url_with_client with expect, panicking with 'Failed to build OAuth URL' when URL construction fails (e.g. no active OAuth client configured or the client's endpoints are missing/invalid). It is a fatal invariant: the function's signature promises a String.

Solutions

1. Ensure an OAuth client is configured and set as active before calling get_auth_url
2. Validate client config fields (valid URLs, non-empty client_id) at load time
3. Refactor get_auth_url to return Result<String, Error> and propagate instead of expect/panic

Example fix

// before
pub fn get_auth_url(redirect_uri: &str, state: &str) -> String {
    get_auth_url_with_client(redirect_uri, state, None)
        .map(|(url, _)| url)
        .expect("Failed to build OAuth URL")
}
// after
pub fn get_auth_url(redirect_uri: &str, state: &str) -> Result<String, OAuthError> {
    get_auth_url_with_client(redirect_uri, state, None)
        .map(|(url, _)| url)
        .map_err(|e| OAuthError::UrlBuild(e.to_string()))
}

if let Err(e) = validate_client_config(&config) { return Err(format!("OAuth client misconfigured: {}", e)); }

let url = get_auth_url_with_client(uri, state, None).map(|(u, _)| u).map_err(|e| eprintln!("oauth url build failed: {e}"))?;

When it happens

Trigger: Calling get_auth_url when no active OAuth client exists, when client_cfg fields (auth_url/client_id) are empty or malformed so Url::parse fails, or any Err from get_auth_url_with_client.

Common situations: App first-run without OAuth client config; config file edited and an endpoint URL broken; get_auth_url called before client initialization completes.
