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

  1. If the final outcome is success, ignore; these lines just trace the polling.
  2. If all attempts fail, address the underlying condition (wrong selector, page never loads) rather than tuning retries.
  3. Increase maxAttempts or interval via the retry options when the wait is legitimately long.
  4. Reduce page/network slowness or stub slow endpoints in tests.
Defensive patterns

Strategy: retry

Prevention

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.
