"tc-bus-api-wrapper": "topcoder-platform/tc-bus-api-wrapper.git"

2. Create an instance of this wrapper with the configuration variables listed below

const busApi = require('tc-bus-api-wrapper')
const busApiClient = busApi(_.pick(config,
      ['AUTH0_URL', 'AUTH0_AUDIENCE', 'TOKEN_CACHE_TIME',
        'AUTH0_CLIENT_ID', 'AUTH0_CLIENT_SECRET', 'BUSAPI_URL',
        'KAFKA_ERROR_TOPIC']))

Configuration / Environment variables:

• Auth0 related variables

  .catch(err => console.log(err))

await busApiClient.postEvent(reqBody)
