Start by tracing the timeout path through src/service/timer-impl.js, src/log.js, and src/utils/promise.js at the lines in the stacktrace. Use the linked error report and the cited historical changes to determine why the task timeout is being reported, then confirm the fix prevents the recurring error without hiding genuine failures.
