Is it possible to mitigate the transient 401 Unauthorized errors occurring in my Playwright TypeScript test suite specifically during the OAuth token refresh window? I am automating E2E scenarios for a custom Genesys Cloud agent desktop extension, and the tests intermittently fail when the access token expires and the interceptor attempts to fetch a new one via the /api/v2/oauth/token endpoint.
The issue appears to be a clock skew between the CI runner (configured to America/Toronto) and the Genesys Cloud authentication servers. When the client sends a refresh request, the nbf (not before) claim in the new token is set slightly in the future relative to the server’s internal clock, causing immediate rejection on subsequent API calls. The error payload returns { "status": 401, "code": "unauthorized", "message": "Token is not yet valid" }, which breaks the page object model’s assumption of a valid session.
I have attempted to add a configurable jitter delay in the Playwright request interception handler before sending the refresh request, but this feels like a band-aid solution that slows down the test execution significantly. The current implementation uses page.route() to capture the 401 response, triggers a custom refreshToken() function, and then retries the original request. However, the retry still fails if the server’s clock is ahead of the client’s clock by more than a few seconds.
Does the Genesys Cloud API documentation specify a recommended tolerance window for clock skew, or is there a specific header I can inject to force the server to use the client’s timestamp for the nbf claim? I need a robust code-based solution that does not rely on arbitrary timeouts, as this impacts the reliability of our CI/CD pipeline. Any insights into handling this specific edge case in the SDK or raw HTTP requests would be appreciated.
