Summary
Fix unhandled promise rejections in
whitespace-async.jsscripts that occur when ESLint 9 loads the config or when CLIEngine is unavailable.Problem
The
onlyErrorOnRules(...).then(...)promise chain lacked a.catch()handler. If the promise rejects, it causes an unhandled rejection, potentially crashing the process. Additionally, child process errors or non-JSON output could causeJSON.parse(stdout)to fail with unclear errors during config loading.Solution
Added
.catch()handlers to log errors to stderr and exit with code 1, ensuring graceful failure and better error visibility.Files Changed
packages/eslint-config-airbnb-base/whitespace-async.jspackages/eslint-config-airbnb/whitespace-async.jsTesting
Verified scripts run without unhandled rejections in both packages.
