Seed error

[Prat1143]

I am trying to create a multi-vendor ecommerce website using medusa js.

Followed all the steps mentioned in - https://github.com/mercurjs/mercur. Then on running the cmd - yarn seed getting the error-

[@mercurjs/vendor-ui] Could not find the admin UI build files. Please run "medusa-admin build" or enable "autoRebuild" in the plugin options to build the admin UI. [@mercurjs/vendor-ui] Exiting process

My medusa-config.js code -

` const dotenv = require('dotenv');

let ENV_FILE_NAME = ''; switch (process.env.NODE_ENV) { case 'production': ENV_FILE_NAME = '.env.production'; break; case 'staging': ENV_FILE_NAME = '.env.staging'; break; case 'test': ENV_FILE_NAME = '.env.test'; break; case 'development': default: ENV_FILE_NAME = '.env'; break; }

try { dotenv.config({ path: process.cwd() + '/' + ENV_FILE_NAME }); } catch (e) {}

// CORS when consuming Medusa from admin const ADMIN_CORS = process.env.ADMIN_CORS || 'http://localhost:7000,http://localhost:7001';

// CORS to avoid issues when consuming Medusa from a client const STORE_CORS = process.env.STORE_CORS || 'http://localhost:8000';

const DATABASE_URL = process.env.DATABASE_URL || 'postgres://localhost/medusa-starter-default';

const REDIS_URL = process.env.REDIS_URL || 'redis://localhost:6379';

const plugins = [ medusa-fulfillment-manual, medusa-payment-manual, { resolve: @medusajs/file-local, options: { upload_dir: 'uploads', }, }, { resolve: '@rigby-software-house/mercurjs-vendor', options: {}, }, { resolve: '@medusajs/admin', options: {}, }, ];

const modules = { /eventBus: { resolve: "@medusajs/event-bus-redis", options: { redisUrl: REDIS_URL } }, cacheService: { resolve: "@medusajs/cache-redis", options: { redisUrl: REDIS_URL } },/ };

/** @type {import('@medusajs/medusa').ConfigModule["projectConfig"]} */ const projectConfig = { jwtSecret: process.env.JWT_SECRET, cookieSecret: process.env.COOKIE_SECRET, store_cors: STORE_CORS, database_url: DATABASE_URL, admin_cors: ADMIN_CORS, // Uncomment the following lines to enable REDIS // redis_url: REDIS_URL };

/** @type {import('@medusajs/medusa').ConfigModule} */ module.exports = { projectConfig, plugins, modules, };

` When I remove the line - { resolve: '@rigby-software-house/mercurjs-vendor', options: {}, },

the yarn seed cmd works fine.

What am I missing here?
