`prompt.version` returns `_xact_id` instead of UI version ID

[gzaripov]

Hi 👋

We’re using the Braintrust TS API to load a prompt:

const prompt = await braintrust.loadPrompt({
  slug,
  apiKey,
  projectName: BRAINTRUST_PROJECT_NAME,
  orgName: BRAINTRUST_ORGANIZATION,
});

When we inspect prompt.version, we get a value like: 1000196486371469912

But in the Braintrust UI, the version shown is something like: 27a571a73aa983e8

So prompt.version seems to return an internal _xact_id, not the short version hash displayed in the UI.

Questions:

1. How can we get the same version ID shown in the UI (27a571a73aa983e8)?
2. Is there another field or endpoint that exposes this version hash?

Thanks!

There's an sdk method called prettifyXact which converts a transaction id into a hash, and loadPrettyXact goes the opposite way.

Could you please export it from the braintrust SDK?

It doesn’t appear to be exported in braintrust@2.0.1 at the moment.

It's available through the /util subpath:

import { prettifyXact } from "braintrust/util";
