I'm working on a very simple project that uses google books API and I have a problem. I want to save all search history in an object in database and all works fine when I'm logged in my account and all history records to a base, but when random user want to find some books I have this error:

enter image description here

How I can fix this?

My code:


        <article class="slds-card">
            <div class="slds-card__header slds-grid">
                <header class="slds-media slds-media_center slds-has-flexi-truncate">
                    <div class="slds-media__body">
                      <h2 class="slds-card__header-title">
                          <span class="slds-text-heading_small slds-truncate slds-align_absolute-center">Books</span>
            <div class="slds-card__body slds-card__body_inner">
                <div class="slds-m-bottom_x-small slds-wrap slds-grid slds-gutters">

                <button class="slds-button slds-button_brand slds-button_stretch" onclick={findBooks}>Find Book(s)</button>

And my Apex class

public without sharing class searchListController {
    public static void addBookRecord(String title, String author){
        if(String.isNotBlank(title) && author != null)
            book_query__c newQuery = new book_query__c();
            newQuery.title_query__c = title;
            newQuery.author_query__c = author;
            newQuery.title_and_author__c = title + author;
            upsert newQuery title_and_author__c;

You need to grant Profile access to the Apex class searchListController. If, as sounds to be the case, you're intending to expose this functionality to unauthenticated users through a public Community, you'd need to add it to the Site Guest User profile for that Community.

Your random user's community profile needs to have access to your apex class, searchListController. Do the same for your guest user's community profile as well if unauthenticated users need to run this component as well.
