Ok, so it works for me <@U0238LE6G2D> Here is my code
```import * as fs from "fs";
import * as path from "path";

let pubKey: string = fs.readFileSync(path.join(__dirname,'/../secret/id_rsa.pub')).toString();
console.log(pubKey);```

When you call `pulumi up` you should get an exception over multiple lines. Do you mind to paste them here please ?

By the way, I initially made a mistake and the exception showed me the full path to my id_rsa.pub Doing a `ls -l "full file path"` revealed my actual mistake.

`import * as pulumi from "@pulumi/pulumi";`
`import * as linode from "@pulumi/linode";`
`const fs = require("fs");`
`const path = require("path");`
`let pubKey: string = fs.readFileSync(path.join(__dirname,'/../secret/id_rsa.pub')).toString();`

`const masterInstance = new linode.Instance("nanode-master", {`
    `group: "masters",`
    `type: "g6-nanode-1",`
    `region: "ap-south",` 
    `image: "linode/alpine3.13",`
    `authorizedKeys: [ pubKey ],`
    `rootPass: "rootPass123!",`
    `tags: ["master node"],`
    `watchdogEnabled: true`
`});`

it works fine if you use console or in express folder. but it pops error when using pubKey as value for authorizedKeys under new instance.

'/../secret/' errors:

`error: Running program '/pulumi' failed with an unhandled exception:`
    `Error: ENOENT: no such file or directory, open '/secret/id_rsa.pub'`

'/../pulumi/' :
No errors, it proceeds to ask if I want to create instance. Both pubKey under pulumi &amp; secret folder are at chmod 777 permission.
