fix(sync): retry transient 5xx errors in fetchWithRetry - #246
Merged
Conversation
Fixes #245. - Extend fetchWithRetry to retry HTTP 500, 502, 503, 504 with exponential backoff (1s, 2s, 4s, capped at 30s) - Previously only 429 (rate-limit) was retried; a momentary Discourse 500 or 502 counted as a hard failure and exceeded MAX_TOLERATED_FAILURES=1 - Update pagination tests in refresh-discussions to use fake timers so 5xx chunk failures exhaust retries without real-time waits - Add five new fetchWithRetry unit tests covering the 5xx retry path Signed-off-by: Sinduri Guntupalli <sinduri.guntupalli@dynatrace.com>
