Load secret from Vault only once when initializing

[stephanebruckert]

I'm using https://github.com/auth0/nextjs-auth0/ but I don't think it matters too much.

I'm trying to fetch a secret from Vault using async/await but I get a Promise { <pending> }

What is the proper way to do this?

// utils/auth0.js

async function getSecretFromVault() {
  const res = await client.fetchSecret();
  console.log(res);  // shows my secret correctly
  return res;
}

const secret = getSecretFromVault();
console.log(secret);  // shows Promise { <pending> }

export default initAuth0({
  clientId: "my_ID",
  clientSecret: secret  // this will be invalid: UI shows "client_id is required"
  ....
});

Would a plugin help doing that maybe?

The problem is similar (or even worse) if I try to do this in server/config.ts, because it complains about top-level awaits.

Also asked here auth0/nextjs-auth0#167 and here https://stackoverflow.com/questions/63868754/fetch-secret-from-vault-when-initializing-next-js. Any really help very appreciated, cheers
