Bug

Instrumentation causing AI_NoOutputGeneratedError on aborts

Reproduction

• Expected behavior is a regular instrumented stream abort without an AI_NoOutputGeneratedError or Sentry error event.
• Reproduction artifacts examples/ai-functions/src/reproduction/issue-8676.ts and examples/ai-functions/src/reproduction/issue-8676-sentry-init.ts tested the checked-out ai@6.0.238 build with standard OpenTelemetry and Sentry's default VercelAI instrumentation using @sentry/node@10.53.1.
• Standard OpenTelemetry produced an abort stream part, called onAbort once, did not call onError or onFinish, and produced no unhandled rejection.
• Sentry instrumentation produced the same abort callbacks and an internal unhandled AbortError, but captured zero Sentry error events; the reported AI_NoOutputGeneratedError was not observed.
• packages/ai/src/generate-text/stream-text.ts now rejects aborted result promises with the abort signal reason instead of NoOutputGeneratedError when no step completes.
• Sentry fixed the reported monitoring impact by ignoring both AI SDK v5 AI_NoOutputGeneratedError and AI SDK v6 AbortError abort rejections; upgrading from the reported @sentry/node@10.12.0 to the tested 10.53.1 resolves the Sentry-visible error without AI SDK product changes.
• The exact Azure Monitor configuration was not supplied; the equivalent active standard OpenTelemetry comparison did not exhibit the reported failure.
• @sentry/node@10.53.1 was added to examples/ai-functions/package.json and pnpm-lock.yaml for the runnable comparison.
