Vue.js array successfully updated based on the current status of the API

I am a beginner in Vue.js and I am working on calling an API. It is functioning perfectly, but I need to update the Vue.js array based on a condition of the API response. However, when trying to do so, I encounter the error "do not mutate vuex store state outside mutation handlers." How can I resolve this issue?

 axios.post(baseUrl+'/api/v1/addProductWishlist', pitem,
                {headers: {
                'Authorization': 'Bearer ' + x,
               'Content-Type':'application/json'
              }
              }).then(r => {
                  if(r.data.status == 202)
                  {
                    
                  }
                  else{
                    state.cartItems.push(payload);

                  }
              });

It is crucial to adhere to the correct pattern when using Vuex for state management. Updating the state should only be done from within a mutation, as this is key to maintaining reactivity and ensuring predictability in large applications. Failure to follow this guideline can result in issues with tracking changes to the state.

A recommended practice is to organize mutations, actions, and API calls into separate files. Actions serve as functionality managers, triggering API calls from an external file before updating the state via mutations.

// actions.js
{
  myAction: async ({ commit }) => {
    const response = await myApiCall();
    if (response.data.status == 202) { ... }
    else {
      commit('ADD_CART_ITEM', response.item)
    }
  }
}

// api.js
export function myApiCall() {
  return axios.post(...)
}

// mutations.js
{
  ADD_CART_ITEM: (state, payload) => state.cartItems.push(payload);
}
