What is the syntax to parse an S3 .json file into individual environment variables in the Serverless.ts configuration?

I’ve tried the following without success to get the environment variable MY\_SECRET set to the value of MY\_SECRET in the bucket’s JSON.

```
functions: {
    hello: {
      environment: {
        MY_SECRET: "${s3:my-config/services/test/support-portal-api.json}"
      },

```

…this deploys but sets MY\_SECRET to the entire contents of the JSON file

```
functions: {
    hello: {
      environment: {
        MY_SECRET: JSON.parse("${s3:my-config/services/test/support-portal-api.json}").MY_SECRET
      },

```

…this fails to deploy with :

```
SyntaxError: Unexpected token $ in JSON at position 0
      at JSON.parse (<anonymous>)

```

What is the correct syntax? The documentation isn’t very clear. Please note this is a Typescript (Serverless.ts) file.

Hi there!

I have solved this using require and ‘magic quotes’.

My project structure is:

```auto
My root folder:
| - config
| |-- dev.json
| |-- prd.json

```

I simply use `require` at the beginning of my serverless.ts file:

```auto
const env = require(`./config/${process.env.STAGE||'dev'}.json`);
console.log('env: ', env);

```

Then, I use it as a JSON object in the environment section:

```auto
    environment: {
      AWS_NODEJS_CONNECTION_REUSE_ENABLED: '1',
      NODE_OPTIONS: '--enable-source-maps --stack-trace-limit=1000',
      CLIENT_ID: env.CLIENT_ID,
      MNG_CLIENT_ID: env.MNG_CLIENT_ID,
      PRIVATE_KEY: env.PRIVATE_KEY,
      HOST: env.HOST,
      ORIGIN: env.ORIGIN,
      RPID: env.RPID,
      INCODE_URL: env.INCODE_URL,
      INCODE_API_KEY: env.INCODE_API_KEY,
      INCODE_FLOW_ID: env.INCODE_FLOW_ID,
    },

```
