Tactics · Dev.to · stat: HTTP 500
Next.js developers risk complete application outages by awaiting background worker boots inside the register() instrumentation hook. A stuck Postgres database lock error propagates through the awaited hook, causing Next.js to abort the entire web server. Removing the await keyword isolates the background worker failure and prevents database timeouts from triggering HTTP 500 errors.
Never let background worker failures share your web server's failure domain Removing the await keyword from Next.js instrumentation hooks prevents database lock issues from escalating into complete front-end outages.
