A transaction made no progress for `timeoutMs`, or hit the hold cap; it rolled back.

## What to do

The transaction made no progress for `timeoutMs` (10000 by default), or once it held the display, the hold lasted that long; it rolled back. Do slow non-runtime work (a `fetch`, a prompt to the shopper) before [`session.transaction(work)`](../api/Session.transaction.md) opens and only `tx` writes inside it; raise [`TransactionOptions.timeoutMs`](../api/TransactionOptions.timeoutMs.md) only for runtime loads that need longer.

```ts
const quote = await fetch('/api/quote').then((r) => r.json() as Promise<{ material: string }>);
await session.transaction(async (tx) => { await tx.select(fabricGroup, quote.material); });
```

The set is open: handle a code you don't know (`'other'`).
