I am trying to send the following string using Mender [Configure](https://docs.mender.io/add-ons/configure):

- `abc ${def} ghi`

However, when I check the received value on the device, it appears as:

- `abc ghi`

It seems that Mender Configure removes any content enclosed within `${}`.

#### Question:

Does Mender Configure not support sending values containing `${}`? If so, is there any way to escape or preserve them?

#### Steps to Reproduce:

1. In the Mender UI, go to **Configuration** , set the key to `test`, and the value to `abc ${def} ghi`.
2. Click **SAVE AND APPLY TO DEVICE**.
3. Check the content of `/var/lib/mender-configure/device-config.json` on the device.

```auto
# cat /var/lib/mender-configure/device-config.json | jq .test
"abc ghi"

```
