From 407c52021bc2ef1659224001cc18f039c2ab37da Mon Sep 17 00:00:00 2001 From: fderuiter <127706008+fderuiter@users.noreply.github.com> Date: Tue, 24 Feb 2026 18:40:02 +0000 Subject: [PATCH 1/4] feat: Enable retries for 5xx/429 and fix error reporting - Update `DefaultRetryPolicy` to retry on 429, 500, 502, 503, 504 status codes. - Modify `SyncRequestExecutor` and `AsyncRequestExecutor` to handle `tenacity.RetryError` correctly when the last attempt was a valid response. - Ensure that `ServerError` and `RateLimitError` are raised after retries are exhausted, instead of a generic `RequestError`. - Update tests to assert that retries occur for these status codes. Impact: - Fixes flaky behavior on transient server errors. - Improves error clarity for developers by surfacing the actual server response. - Increases reliability of long-running operations.
