TypeError: vaultEnv.on is not a function

[iiro]

Hi!

I noticed an issue when trying to use the lease-"monitoring":

➜  example node app.js
vault-env: fetching 3 secrets from http://localhost:8210/
vault-env: loading TEST_DB_USERNAME, TEST_DB_PASSWORD from postgres/creds/myrole ✓
Example app listening at http://localhost:8080
My test secret is: secret_value2
/Users/username/checkouts/vault/apps/node/example/app.js:22
  vaultEnv.on("DATABASE_URL", function (newDB, oldDB) {
           ^

TypeError: vaultEnv.on is not a function
    at Server.<anonymous> (/Users/username/checkouts/vault/apps/node/example/app.js:22:12)
    at Object.onceWrapper (node:events:513:28)
    at Server.emit (node:events:394:28)
    at emitListeningNT (node:net:1349:10)
    at processTicksAndRejections (node:internal/process/task_queues:82:21)

Is there something "obvious" to fix - either in the example in the README or in code...?

Running NodeJS v16.6.1 here.

Just writing this to myself: this is needed only for static secrets, I think... As with leased secrets, there's no need to "watch"...
