&gt;  <@U06CCB0EUBC> Facing a similar issue. Did you use an environment variable when using an array kind in the config?

<@U06CCB0EUBC> I am using array kind in the settings, but the env variable is not being interpolated correctly.  Here is the example, where “${GOOGLE_ADS_DEVELOPER_TOKEN}” is the string literal that appear after I output the config.json for the tap:

```settings:
  - name: login_customer_ids
    kind: array
config:
  login_customer_ids:
    - customerId: "${GOOGLE_ADS_CUSTOMER_ID}"
      loginCustomerId: "${GOOGLE_ADS_CUSTOMER_ID}"```

```{
  "login_customer_ids": [
    {
      "customerId": "${GOOGLE_ADS_CUSTOMER_ID}",
      "loginCustomerId": "${GOOGLE_ADS_CUSTOMER_ID}"
    }
  ]
}```

I am trying to get something like this:
```{
  "login_customer_ids": [
    {
      "customerId": "12345",
      "loginCustomerId": "12345"
    }
  ]
}```

Normally you use env variables directly using `.env` or env variables

Check out <https://docs.meltano.com/guide/configuration#configuration-layers>

Let me know if you do/don't get there and how :smile:

someone else may be able to help more too :wink:

got this to work by using a string representation in the config block:
```login_customer_ids: "[{\"customerId\": \"${GOOGLE_ADS_CUSTOMER_ID}\", \"loginCustomerId\": \"${GOOGLE_ADS_CUSTOMER_ID}\"}]"```
