When _update_access_token() fails because the refresh token is expired or invalid, the current code logs an error and stops — leaving the user with no working tokens and no way to recover without manual intervention.
This change adds a fallback: if the access token refresh request fails (HTTP error from Schwab's OAuth endpoint), the code automatically triggers _update_refresh_token() to start the full re-authorization flow, allowing the user to re-authenticate and obtain fresh tokens.
What changed in schwabdev/tokens.py:
In _update_access_token(): when the refresh token POST returns an error response, instead of silently returning, it now logs a warning and calls _update_refresh_token() to initiate the full OAuth authorization code flow.
Why:
Refresh tokens expire after 7 days. If an application is idle beyond that window, the access token refresh silently fails with no recovery path — the user must manually restart or re-authenticate. This fix makes token recovery automatic.
