Should be
```
Object.assign({}, FORM_DATA_DEFAULTS, metrics);
```
To create a copy and put all the fields of `FORM_DATA_DEFAULTS` and `metrics`
into the new object.
The current code will modify `FORM_DATA_DEFAULTS`.
You can also use this object spread notation
```
const formData = { ...FORM_DATA_DEFAULTS, ...metrics }
```
