Async Request Timeout on Replit
Asynchronous requests timeout before completing, even though operation should finish quickly. Async operations hang indefinitely.
Misconfigured timeout values or blocking operations in async code cause hangs.
Error Messages You Might See
Common Causes
- Timeout value too short for actual operation time
- Blocking operation on async thread
- Deadlock in async task handling
- Thread pool exhausted, tasks queued indefinitely
- Missing error handling for timeout exception
How to Fix It
Set appropriate timeouts based on operation nature (5-30s). Use non-blocking async libraries (WebClient, Mono, Flux). Configure thread pool appropriately. Implement proper exception handling for TimeoutException. Use CompletableFuture.orTimeout() or Flux.timeout() for time limits. Monitor thread pool metrics.
