nuxt vuex：不要在變異處理程序之外改變 vuex 存儲狀態

為什麼我會收到此錯誤：

錯誤 [vuex] 不要在變異處理程序之外改變 vuex 存儲狀態

當我調用這個組件時會發生這種情況。

問題出現在這個突變 - this.startCodeTimer (30);

突變文件：

export default {
  setAuthResponse(state, data) {
    state.authResponse = data
  },
  setCodeResponse(state, data) {
    state.codeResponse = data
  },
  setRegResponse(state, data) {
    state.regResponse = data
  },
  setAuthCode(state, data) {
    state.authCode = data
  },
  startCodeTimer(state, time) {
    state.newCodeTimer = time
    state.codeTimerId = setInterval(() => {
      if (state.newCodeTimer) {
        state.newCodeTimer--
      } else {
        clearInterval(state.codeTimerId)
      }
    }, 1000)
  },
  resetCodeTimer(state) {
    state.newCodeTimer = 0
  }
}

如果我理解正確，那麼問題就在這裡。

state.codeTimerId = setInterval(() => {
      if (state.newCodeTimer) {
        state.newCodeTimer--
      } else {
        clearInterval(state.codeTimerId)
      }
    }, 1000)

但到目前為止還沒有想法如何解決它。
