"format" doesn't exist in prompt's body types

Description

I am trying the default sdk session prompt and i am getting a type issue when trying to pass a structured output format schema, the execution however works fine, it is just a type issue.
here is my code, nothing special here :

import { createOpencodeClient } from "@opencode-ai/sdk";

const start = async () => {
  const opencodeClient = createOpencodeClient({
    baseUrl: "http://localhost:4096",
  });

  const session = await opencodeClient.session.create();

  const result = await opencodeClient.session.prompt({
    path: { id: session.data?.id! },
    body: {
      parts: [
        { type: "text", text: "Research Anthropic and provide company info" },
      ],
      format: {
        type: "json_schema",
        schema: {
          type: "object",
          properties: {
            company: { type: "string", description: "Company name" },
            founded: { type: "number", description: "Year founded" },
            products: {
              type: "array",
              items: { type: "string" },
              description: "Main products",
            },
          },
          required: ["company", "founded"],
        },
      },
    },
  });
};

from the generated types, format is not there

// @opencode-ai/sdk/dist/gen/types.gen.d.ts
export type SessionPromptData = {
    body?: {
        messageID?: string;
        model?: {
            providerID: string;
            modelID: string;
        };
        agent?: string;
        noReply?: boolean;
        system?: string;
        tools?: {
            [key: string]: boolean;
        };
        parts: Array<TextPartInput | FilePartInput | AgentPartInput | SubtaskPartInput>;
    };
    path: {
        /**
         * Session ID
         */
        id: string;
    };
    query?: {
        directory?: string;
    };
    url: "/session/{id}/message";
};
