Summary

  • Adds retry with exponential backoff to the testing token fetch in @clerk/testing
  • Retries up to 5 times on transient HTTP errors (408, 429, 500, 502, 503, 504) with exponential backoff + jitter
  • Retries on network-level errors (ECONNREFUSED, ECONNRESET, ENOTFOUND, ETIMEDOUT, EAI_AGAIN)
  • Respects Retry-After headers when provided, with all delays capped at 30s
  • Retry attempts emit warning logs with status/error code, attempt count, and wait time
  • Adds unit tests for the retry logic covering all retry/non-retry paths

Why

fetchEnvVars calls testingTokens.createTestingToken() without retry handling, causing E2E test failures when FAPI returns 429 (Too Many Requests) under concurrent test workers or when transient network issues occur against staging.

Test plan

  • @clerk/testing builds successfully
  • 19 unit tests covering retryable HTTP statuses, network errors, max retries, retryAfter handling, non-retryable errors, and existing token bypass
  • Run E2E tests with concurrent workers to confirm 429s are retried instead of failing immediately

📝 Walkthrough

Walkthrough

Added a generic fetchWithRetry(fn, label) wrapper and an isClerkAPIResponseError type guard. fetchWithRetry retries failed async operations up to MAX_RETRIES + 1 attempts when the error is a Clerk API response with status in {408, 429, 500, 502, 503, 504} or a network-like error with code in {ECONNREFUSED, ECONNRESET, ENOTFOUND, ETIMEDOUT, EAI_AGAIN}. Retry delay uses error.retryAfter (seconds→ms, capped) for Clerk errors or exponential backoff with jitter (capped) otherwise. Each retry logs a console.warn; non-retryable errors or exhausted attempts rethrow the error.

Summary

  • Adds retry with exponential backoff to the testing token fetch in @clerk/testing
  • Retries up to 5 times on transient HTTP errors (408, 429, 500, 502, 503, 504) with exponential backoff + jitter
  • Retries on network-level errors (ECONNREFUSED, ECONNRESET, ENOTFOUND, ETIMEDOUT, EAI_AGAIN)
  • Respects Retry-After headers when provided, with all delays capped at 30s
  • Retry attempts emit warning logs with status/error code, attempt count, and wait time
  • Adds unit tests for the retry logic covering all retry/non-retry paths

Why

fetchEnvVars calls testingTokens.createTestingToken() without retry handling, causing E2E test failures when FAPI returns 429 (Too Many Requests) under concurrent test workers or when transient network issues occur against staging.

Test plan

  • @clerk/testing builds successfully
  • 19 unit tests covering retryable HTTP statuses, network errors, max retries, retryAfter handling, non-retryable errors, and existing token bypass
  • Run E2E tests with concurrent workers to confirm 429s are retried instead of failing immediately

📝 Walkthrough

Walkthrough

Added a generic fetchWithRetry(fn, label) wrapper and an isClerkAPIResponseError type guard. fetchWithRetry retries failed async operations up to MAX_RETRIES + 1 attempts when the error is a Clerk API response with status in {408, 429, 500, 502, 503, 504} or a network-like error with code in {ECONNREFUSED, ECONNRESET, ENOTFOUND, ETIMEDOUT, EAI_AGAIN}. Retry delay uses error.retryAfter (seconds→ms, capped) for Clerk errors or exponential backoff with jitter (capped) otherwise. Each retry logs a console.warn; non-retryable errors or exhausted attempts rethrow the error.

📝 Walkthrough

Walkthrough

Added a generic fetchWithRetry(fn, label) wrapper and an isClerkAPIResponseError type guard. fetchWithRetry retries failed async operations up to MAX_RETRIES + 1 attempts when the error is a Clerk API response with status in {408, 429, 500, 502, 503, 504} or a network-like error with code in {ECONNREFUSED, ECONNRESET, ENOTFOUND, ETIMEDOUT, EAI_AGAIN}. Retry delay uses error.retryAfter (seconds→ms, capped) for Clerk errors or exponential backoff with jitter (capped) otherwise. Each retry logs a console.warn; non-retryable errors or exhausted attempts rethrow the error.

Summary

  • Adds retry with exponential backoff to the testing token fetch in @clerk/testing
  • Retries up to 5 times on transient HTTP errors (408, 429, 500, 502, 503, 504) with exponential backoff + jitter
  • Retries on network-level errors (ECONNREFUSED, ECONNRESET, ENOTFOUND, ETIMEDOUT, EAI_AGAIN)
  • Respects Retry-After headers when provided, with all delays capped at 30s
  • Retry attempts emit warning logs with status/error code, attempt count, and wait time
  • Adds unit tests for the retry logic covering all retry/non-retry paths

Why

fetchEnvVars calls testingTokens.createTestingToken() without retry handling, causing E2E test failures when FAPI returns 429 (Too Many Requests) under concurrent test workers or when transient network issues occur against staging.

Test plan

  • @clerk/testing builds successfully
  • 19 unit tests covering retryable HTTP statuses, network errors, max retries, retryAfter handling, non-retryable errors, and existing token bypass
  • Run E2E tests with concurrent workers to confirm 429s are retried instead of failing immediately
