.catch(err => console.log('Error: ' + err))I am using the above code to make connection to postgres database. But I am receiving below error on execution of node index command, index.js is not attached here. I want dbUSerName and dbUserpassword values to be passed in the sequelize connection string after fetched from the vault. but the values are promise which I am not able to resolve.
error: uncaughtException: The "string" argument must be of type string or an instance of Buffer or ArrayBuffer. Received an instance of Promise
credential function returns Promise, you need to call it as a promise function.
You can read about promises here https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise
I think it will be better to wrap your code in a async function and use await before calling credential
async function main() {
const dbUserName = await credential(constants.pgDbUserName);
const dbPassword = await credential(constants.pgDbPassword);
// Your code
}
main();
