I am writing different JS functions to post, delete and get flows, and my flow is using the s3 out node.  
I am using the variables `${awsConfig}` and `${s3Bucket}` to hold values for `aws` and `bucket`.

When I run the js file which has my `postFlow` function and check my nodered editor, I see the correct bucket name as specified in my flow json file with `${s3Bucket}`, but I get a warning/error `invalid properties -aws` for the aws field.

When I replace `${awsConfig}` with hardcoded `123edhks2378js` and rerun my function, the message goes away.

When I input my `AccessKeyID` and `Secret Access Key` in the editor and export my flow, i see `aws: " "` in my json file, so there's no way for me to see or understand how this configuration works - which I assume is for security reasons.

My questions are:

1. Is there a way for me to export my `AccessKeyID` and `Secret Access Key` from my request body in a javascript function?

2. Also, if it's successfully exporting the bucket name and the warning message goes away when I hardcode the value of `${awsConfig}` in my json, why can't it just read and use this? `const awsConfig = "123edhks2378js"`

Here's a snippet of my flow (this is just the **s3 out node** ) and the way I declared the variables in the js file.

```auto
const awsConfig = "123edhks2378js"
const s3Bucket = "xyz"

```

```auto
  id: "dea435a278I882655",
      type: "amazon s3 out",
      z: "bb50d86374bc1547",
      aws: `${awsConfig}`,
      bucket: `${s3Bucket}`,
      filename: "",
      localFilename: "",
      region: "us-west-2",
      name: "Upload to S3",
      x: 1330,
      y: 400,
      wires: [],

```
