## What this fixes
Reading a completed transcript raised `pydantic_core._pydantic_core.ValidationError: 1 validation error for TranscriptResponse` with `chapters.0.gist` and `Field required [type=missing, ...]`, because the API returned chapter objects without a `gist` key while the SDK model required it. The reporter's own response JSON showed the missing key plainly. Maintainer ccampbell-aai confirmed the fix landed in PR #162: upgrade to any SDK version above 0.49, with 1.1.0 being the latest at the time.
## The fix
This validation error means the API returned chapters without the `gist` field that your SDK version requires. It was fixed in PR #162, so upgrade to any assemblyai version above 0.49. The failure happens when deserializing the transcript response, not during transcription itself, so your audio processing is fine. Pin above 0.49 in your requirements to keep this from coming back.

## Why it happens
The thread above nails the cause, so the fix addresses that directly rather than symptoms. Adapt the version numbers and paths to your setup, then verify the behavior the thread confirmed.
