Как перебрать массив rounds в апи поле

есть такой код:

<script>
import axios from "axios";

export default {
  data() {
    return {
      rounds: [],
      matches:[]
    }
  },
  created() {

    axios.get(`https://api.sportsdata.io/v3/csgo/scores/json/CompetitionDetails/${this.$route.params.competitionId}?key=`)
        .then(response => {
          response.data.Seasons.forEach(season => {
            season.Rounds.forEach(round => {
              if (this.$route.params.seasonId == round.SeasonId){
                this.rounds.push(round.RoundId)
              }
            })
          })
        })

    this.rounds.forEach(roundId => {

    axios.get(`https://api.sportsdata.io/v3/csgo/scores/json/Schedule/${roundId}?key=`)
        .then(response => {
          this.matches.push(response.data)
        })
    })
  },
}
</script>

нужно вставить каждый элемент массива this.rounds в https://api.sportsdata.io/v3/csgo/scores/json/Schedule/{roundid} Почему-то массив this.matches пустой
