how to get shared variables?

Question

hello, been trying to use railway to deploy a discord.js bot, but i can't seem to get my token working.

GitHub understandably won't let me upload a discord token to my repo, since other people could see it and mess with my bot, so i'm tryna figure out shared variables.
i put my token as a shared variable on my project, shared it to my deployment, and i put  `"token":"${{shared.token}}"` into my `config.json`, where my token once was.
(my config.json, where i'm trying to access the variable ↓)
```json
{
 "token": "${{shared.token}}",
 "clientId": "(my bot's ID is here.)"
}
```however, when trying to use `const {token} = require('./config.json')` and deploying it, it says i have an invalid token.
my code is being run on railway, from a GitHub repo.
what exactly am i doing wrong here, and what should i do to get my shared variables?
