Trouble with Scoped Search API Keys in Flutter App

// @ts-check
const Typesense = require("typesense");

// Initialize Typesense client
const typesenseClient = new Typesense.Client({
  // Set the appropriate endpoint and API key for your Typesense instance
  nodes: [
    {
      host: "",
      port: 443,
      protocol: "https", // Use 'https' for secure connection
    },
  ],
  apiKey: "redacted",
});

// Function to generate a scoped search key
async function generateScopedSearchKeyForTypesense(userId, accountId) {
  try {
    // Make sure that the parent search key you use to generate a scoped search key
    //  has no other permissions besides `documents:search`

    // Generate a scoped search API key with embedded filter
    const searchKey = "redacted"; // Replace with your main search API key
    const parameters = {
      filter_by: `accountId:=${accountId}`,
    };
    const scopedSearchKey = await typesenseClient.keys().generateScopedSearchKey(searchKey, parameters);

    // Make sure that the parent search key you use to generate a scoped search key
    //  has no other permissions besides `documents:search`

    // Return the scoped search key
    return scopedSearchKey;
  } catch (error) {
    console.error("Error generating scoped search key:", error);
    throw error;
  }
}

module.exports = generateScopedSearchKeyForTypesense;

// Make sure that the parent search key you use to generate a scoped search key
//  has no other permissions besides `documents:search`
