looping through variable from rest api and ading it to a v-list

Question

I am having some difficulties with the vue.js. The main problem is that I am getting this error :

Property or method `response` is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for `class-based` components, by initializing the property.

My main idea is to loop through the response (which is just an array) and add it to my v-list to have it in shape of something like this :

Instead of having create, read etc. to have my elements of array, and I am wondering how to even start with this problem.

like this is the part with my list in vue.js, I know that I think I need to use v-for method but I cant even start it without solving the error.

            <v-list-group>
              <v-list-item @click="getHosts()">
              {{response}}
              </v-list-item>
              <v-list-item-group>
              </v-list-item-group>
            </v-list-group>
          </v-list>

and this is the function that gets the array.

getHosts(){
      axios.get('http://127.0.0.1:8000/something')
      .then((response)=>{
      console.log(response.data)      
      return response
      })
    }

I've added this function in export default in section methods, I've read about other sections and thought maybe beforeMount but I still got an error.

Thanks for any clues/help/solutions!
