Server Error on parse dashboard when configure parse adapter with ios

Question

when i configure ios key on PushAdapter the UI of the dashboard gets server error after login. the request of http://myserver.com/dashboard/parse-dashboard-config.json returns with 500 Internal Server Error and the error on the server is TypeError: Converting circular structure to JSON. this is happening when i add the configuration of ios

const { default: PushAdapter } = require('@parse/push-adapter');
const parseConfig = {
    apps: [
        Object.assign({
            databaseURI,
            cloud: './cloud/main.js',
            serverURL,
            appId,
            masterKey,
            restApiKey,
            javascriptKey,
            appName,
            supportedPushLocales: ['en'],
            production: isProdEnv,
            masterKeyIps: ['0.0.0.0/0'],
            push: {
                adapter: new PushAdapter({
                  ios: [
                  {
                    token: {
                        key: './secrets/ios/my-cert.p8',
                        keyId: '34SW5XLWJ3',
                        teamId: 'ASMXHG4HKJ',
                    },
                    topic: 'com.example.myapp',
                    production: false,
                  },
                 ]
                }),
            }
        })
    ],
    users: [
        {
            user,
            pass
        },
    ],
}

My dependences:

{
  "dependencies": {
    "@parse/push-adapter": "^4.1.2",
    "dotenv": "^8.2.0",
    "express": "^4.17.1",
