I recently migrated to the Vuex store, and I am making a decent amount of progress. But the current challenge I face is calling an action from within another action in Vuex. I am still in the process of learning Vue.js

Current versions

1. Vue 3
2. Vuex 4
3. If needed I use Electron Vue.js dev tools

/src/store/index.js - Current code

/* eslint-disable no-redeclare */

import { createStore } from 'vuex'
import axios from 'axios'

export default createStore({
  state: {
    ...
  },
  mutations: {
    setQuery(state, query) {
      // refers this.state.query
      state.query = query
    },

    setOnlinePresenceInitialPageLoad(state, presence) {
      // refers this.state.online & this.state.initialPageLoad
      state.online = presence
      state.initialPageLoad = false
    },

    setRequestErrorAndStatus(state, { _status, code }) {
      // refers this.state.request.error & this.state.request._status
      state.request.error = _status
      state.request._status = code
    },

    setResults(state, processed) {
      state.request.results = processed
    }
  },
  actions: {
    callApi({ commit, state, dispatch }) {
      axios.get(state.axios.targetURL, {
        baseURL: state.axios.config.baseURL,
        params: {
          days: state.axios.config.params.days,
          q: state.query,
          key: state.axios.config.params.key,
        },
      }).then(response => {
        console.log(response.status)
        commit('setOnlinePresenceInitialPageLoad', true);
        dispatch('formatResults', response.data);
      }).catch(error => {
        if (error.response) {
          console.log(error.response.status)
        } else if (error.request) {
          console.log(error.request.status)
        } else {
          console.log("Couldn't find the problem")
        }
      })
    },
    formatResults(context, payload) {
      const processedData = {
          ...
      }
      console.log(processedData);
      context.commit('setResults', processData);
    }
  },
  modules: {
  }
})

As you can see the callApi() calls the formatResults() in the fulfilled section of the Promise.

Current state (Web browser)

In the code, I tried logging out the variable processedData. I thought it would be printed on the console.

Current state (Vue Devtools)

I would also like to know why formatResults() never ends.

Can this problem be solved with async functions, if yes then I would like to know the procedures to take?

Thanks for the help

hard to tell from the information provided, but I'm going to venture a guess here...

seeing that console.log(response.status) and then console.log("Couldn't find the problem") were triggered, as well as formatResults (from the vuex screenshot) I suspect that formatResults is throwing an error.

formatResults(context, payload) {
  const processedData = {
      // the error could be somewhere here
  }
  console.log(processedData);
  context.commit('setResults', processData);
}

when the error occurs, the catch will handle it

if (error.response) {
  console.log(error.response.status)
} else if (error.request) {
  console.log(error.request.status)
} else {
  // handled here with log ...
  console.log("Couldn't find the problem")
}

try using console.error(error) to see what the cause of the error is

if (error.response) {
  console.log(error.response.status)
} else if (error.request) {
  console.log(error.request.status)
} else {
  console.error(error)
}

and then you might have enough information to debug the source of the problem
