React JS: Unexpected token < in JSON at position 0

I’m trying to parse and get fetch data from URL, but got the error like:

Unexpected token < in JSON at position 0

the URL contains this such of data:

I just used fetch to parse and fetch data like below:

let url = "/geoserver/wfs?service=WFS&version=1.0.0&request=GetFeature&typeName=kict:v_plans_photo&srsName=EPSG:4326&maxFeatures=10000&format_options=callback:getJson&cql_filter=INTERSECTS(geom, POINT (128.9880585 37.7161098))"

if (url) {
    fetch(url, {
       headers : { 
          'Accept': 'application/json'
        }
    })
    .then(response => response.json())
    .then((response) => {
        console.log(response)
     },
     (error) => {
      this.setState({
         isLoaded: true,
         error
       });
       console.log(`fetch failed: ${this.state.error}`)
       }
     )
  }

How can I get data from that URL using fetch?
