Claude Code v2.1.239 ·

Empty API streams get their own error

A stream that ends with no events now reports that specifically rather than a vague error.

What

A response stream that closes without delivering a single event now fails with a specific error, StreamNoEventsError, reading "Stream ended without receiving any events", rather than surfacing as generic stream trouble.

Details
  • Unconditional; applies to any API stream.
Evidence

Stream ended without receiving any events

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
