Working in the Encode and Decode using the NodeJS, I want to Encode the data using the `RS512` algorithm, for using that algorithm I have to pass the secret key as a pem file, so I use require to import that pem file but I cannot able to import that file

The Code that I used is

```js
const secretKey = require("./secretkey.pem");

```

when I import the file like this am getting the error

```
ReferenceError: Invalid left-hand side expression in prefix operation

```

How to solve this issue.
