Hi,  
where I can find accesKeyOrToken to use AccountClient from node.js sdk. I thought that it’s access keys from application section on TTN, but it doesn’t work - “401 unauthorized”.  
Basic case in NodeJS:

> const { account } = require(‘ttn’);  
> const { accessKey } = require(‘./config’);  
> const AccountClient = new account(accessKey);
> 
> const getApp = async () =\> {  
> try {  
> const app = await AccountClient.getApplication();  
> }  
> catch (err) {  
> console.log(new Error(err));  
> }  
> }

getApp();
