retry attempt / failed for
Error message
retry attempt {}/{} failed for: {} What it means
WARN log emitted per failed attempt inside the CDP driver's retry loop: the condition was still not satisfied after attempt N of maxAttempts. The loop continues sleeping and rechecking until attempts are exhausted; a final 'retry FAILED' log follows if all attempts fail.
Solutions
- If the final outcome is success, ignore; these lines just trace the polling.
- If all attempts fail, address the underlying condition (wrong selector, page never loads) rather than tuning retries.
- Increase maxAttempts or interval via the retry options when the wait is legitimately long.
- Reduce page/network slowness or stub slow endpoints in tests.
Defensive patterns
Strategy: retry
Prevention
- Size maxAttempts × interval to comfortably exceed the app's worst-case render time.
- Fix flaky selectors (avoid brittle dynamic ids) so conditions pass sooner.
When it happens
Trigger: Condition Supplier returns false/null on attempt N during the retry loop — each sleep(interval)/check cycle that does not satisfy the condition logs this line.
Common situations: Waiting for an element that renders slowly; waiting on network idle with a chatty page; expecting a URL change that happens later than the interval; slow CI runners.
Understand the failure class
Background: Request timed out: what client-side request timeouts mean across libraries (Request timed out, TIMED_OUT, APITimeoutError) — this error's family across 39 libraries.
