Data event return empty data object in JS client

[gsbm]

Describe the bug

Hi,
When executing this specific request with Gradio JS client, the data event is well streamed by the server but not handled by the client, it return empty data: [].
This problem occurs both on submit() and predict(). First time I meet this issue by working with Gradio API.
Please note that this is working fine with Python client.

Reproduction

Script :

import { Client, handle_file } from "@gradio/client";

async function generate(image_url) {

    const client = await Client.connect("TencentARC/InstantMesh", {
        events: ["status", "data"]
    });

    const image = await fetch(image_url);
    const image_blob = await image.blob();

    // This is working fine
    const result_mvs_image = await client.predict("/generate_mvs", [
        handle_file(image_blob),
        50,
        10000,
    ]);

    // This is returning empty data object
    const job = client.submit("/make3d", []);

    for await (const message of job) {
        if (message.type === "status") {
            // ....    
        }
        if (message.type === "data") {
            console.log(JSON.stringify(message));
        }
    }
}
