ERROR @wdio/local-runner: Failed launching test session: TypeError: ReporterClass is not a constructor

[MahaJampala]

I am trying to add allure reporting to the framework.
I am getting an error message "ERROR @wdio/local-runner: Failed launching test session: TypeError: ReporterClass is not a constructor"

This is my wdio.conf.js

const path = require("path");
exports.config = {
//
// ====================
// Runner Configuration
// ====================
//
runner: 'local',
port: 4723, // default appium port
services: [
[
'appium',

command: 'appium'
}
]
],
//
// ==================
// Specify Test Files
// ==================
// Define which test specs should run. The pattern is relative to the directory
// from which wdio was called.
//
// The specs are defined as an array of spec files (optionally using wildcards
// that will be expanded). The test for each spec file will be run in a separate
// worker process. In order to have a group of spec files run in the same worker
// process simply enclose them in an array within the specs array.
//
// If you are calling wdio from an NPM script (see https://docs.npmjs.com/cli/run-script),
// then the current working directory is where your package.json resides, so wdio
// will be called from there.
//
specs: ["./test/specs/AppLogin.js"],

exclude: [
// 'path/to/excluded/files'
],
//
// ============
// Capabilities
// ============
// Define your capabilities here. WebdriverIO can run multiple capabilities at the same
// time. Depending on the number of capabilities, WebdriverIO launches several test
// sessions. Within your capabilities you can overwrite the spec and exclude options in
// order to group specific specs to a specific capability.
//
// First, you can define how many instances should be started at the same time. Let's
// say you have 3 different capabilities (Chrome, Firefox, and Safari) and you have
// set maxInstances to 1; wdio will spawn 3 processes. Therefore, if you have 10 spec
// files and you set maxInstances to 10, all spec files will get tested at the same time
// and 30 processes will get spawned. The property handles how many capabilities
// from the same test should run tests.
//
maxInstances: 10,
//
// If you have trouble getting all important capabilities together, check out the
// Sauce Labs platform configurator - a great tool to configure your capabilities:
// https://saucelabs.com/platform/platform-configurator
//
capabilities: [
{
platformName: "Android",

},
],
//
// ===================
// Test Configurations
// ===================
// Define all options that are relevant for the WebdriverIO instance here
//
// Level of logging verbosity: trace | debug | info | warn | error | silent
logLevel: "debug",
//
// Set specific log levels per logger
// loggers:
// - webdriver, webdriverio
// - @wdio/browserstack-service, @wdio/devtools-service, @wdio/sauce-service
// - @wdio/mocha-framework, @wdio/jasmine-framework
// - @wdio/local-runner

//
// If you only want to run your tests until a specific amount of tests have failed use
// bail (default is 0 - don't bail, run all tests).
bail: 0,
//
// Set a base URL in order to shorten url command calls. If your url parameter starts
// with /, the base url gets prepended, not including the path portion of your baseUrl.
// If your url parameter starts without a scheme or / (like some/path), the base url
// gets prepended directly.
baseUrl: "http://localhost",
//
// Default timeout for all waitFor commands.
waitforTimeout: 10000,
//
// Default timeout in milliseconds for request
// if browser driver or grid doesn't send response
connectionRetryTimeout: 120000,
//
// Default request retries count
connectionRetryCount: 3,
//
// Test runner services

// your test setup with almost no effort. Unlike plugins, they don't add new
// commands. Instead, they hook themselves up into the test process.

// =====
// Hooks
// =====
// WebdriverIO provides several hooks you can use to interfere with the test process in order to enhance
// it and to build services around it. You can either apply a single function or an array of
// methods to it. If one of them returns with a promise, WebdriverIO will wait until that promise got
// resolved to continue.

Can someone help me with this
