</ParamField>

<ParamField path="settings" type="Partial<{…}>">
  (Optional) Weave tracing settings

  Full type: `Partial<{ attributes: Record<string, any>; genai: { batchOptions?: BufferConfig; spanProcessor?: "batch" | "simple" | SpanProcessor; }; printCallLink: boolean; useCallsComplete: boolean; useOTelV2: boolean; }>`
</ParamField>

## Returns

`Promise`\<[`WeaveClient`](../interfaces/weaveclient)>

A promise that resolves to the initialized Weave client.

## Throws

If the initialization fails
