Get Value from JSON Array Rest Sensor

Hi. I’m trying to extract the value from some JSON at a URL. I am able to get some of the contents to display in Home Assistant, but the values from the array in the JSON (which is what I am really after) displays as unknown.

For instance at this URL:

https://waterservices.usgs.gov/nwis/iv/?sites=05514705&period=P7D&format=json

I want to retrieve the latest river gage level.

This path returns the correct value in this JSONTesterr:

.value.timeSeries[0].values[0].value[667].value

So I would think that {{ 'value_json.value.timeSeries[0].values[0].value[667].value' }} would return the same value, but nope. I have been working on this for a few days with no luck. I would really like to do this natively in Home Assistant without invoking BeautifulSoup if possible. Any suggestions?

Here is my REST sensor setup:

  - platform: rest
    name: quivre
    resource: https://waterservices.usgs.gov/nwis/iv/?sites=05514705&period=P7D&format=json
    value_template: '{{ value_json.value.timeSeries[0].values[0].value[667].value }}'
    verify_ssl: false
