File Search's config not properly working in Client side

Hello, I’m trying utilize Gemini’s File search API in Tauri Application with below code.

// <TAURIPROJECT>/src/main.js
async function handleFileUpload(event) {
  const ai = new GoogleGenAI({
    apiKey: "YOUR_API_KEY", // Replace with your actual API key
  });

  const button = event.target;
  const storeName = button.getAttribute("data-store-name");

  try {
    const filePath = await open({ // from "@tauri-apps/plugin-dialog";
      multiple: false,
      directory: false,
    });

    const fileData = await readFile(filePath); // from "@tauri-apps/plugin-fs";
    const fileBlob = new Blob([fileData]);
    const filePath_print = filePath.split("/").pop();

    let operation = await ai.fileSearchStores.uploadToFileSearchStore({
      file: fileBlob,
      fileSearchStoreName: storeName,
      config: {
        displayName: filePath_print, // THIS NOT WORKING EVEN WITH SOME FIXED STRING
      },
    });

    while (!operation.done) {
      await new Promise((resolve) => setTimeout(resolve, 5000));
      operation = await ai.operations.get({ operation });
    }        
  } 
}

I used file selector of Tauri application, and get file’s path and read it as Blob object; since browser of tauri didn’t support file path directly ([Error] File path is not supported in browser uploader)

[RESULT] It seems working well, but the displayName in config didn’t work properly, below is console.log of documents.list of fileSearchStores API:

const documents = await ai.fileSearchStores.documents.list({

      parent: store.name,

    });

Object

createTime: "..."

mimeType: "application/pdf"

name: "fileSearchStores/SOMEPATH"

sizeBytes: "8697299"

state: "STATE_ACTIVE"

updateTime: "..."

[EXPECTED] Which worked fine in just running js code with node command.

Object

createTime: “...”

displayName: “note.pdf”

mimeType: “application/pdf”

name: “fileSearchStores/SOMEPATH”

sizeBytes: “8697299”

state: “STATE_ACTIVE”

updateTime: “…”

The different point from example code is 2 thing.

1: I used fileblob not filepath

2: I used npm run tauri dev instead of node main.js

Do you have any idea to solve this problem?

Thanks
