Those field are part of standard 'BillingAddress' and 'ShippingAddress' fields of Account Object. 

You might not be able to find it in Object Manager, but they are part of Address fields. Please use ShippingPostalCode and BillingPostalCode as fields and it will work. 

You can verify their existince using SOQL query, Workbench or Salesforce Inspector or any similar tools. Address is a compound field consisting of Street,City,State.PostalCode etc. 

I am assuming you are working on this module https://trailhead.salesforce.com/content/learn/projects/get-started-with-salesforce-development/build-reusable-ui-component-with-lightning-web-components

The PROBLEMS tab is explicitly telling you that it has found 7 distinct errors or warnings within the files of your project. A Lightning Web Component with even a single syntax error in its HTML or JavaScript file cannot be successfully deployed to a Salesforce org.

From module

import { LightningElement, wire } from "lwc";
import getHouses from "@salesforce/apex/HouseService.getRecords";
export default class HousingMap extends LightningElement {
    mapMarkers;
    error;
    @wire(getHouses)
    wiredHouses({ error, data }) {
        if (data) {
        console.log(data);
    }
  }
}

Part 2: Immediately after, the instructions say: "Next, let's add code to transform the data... Replace the code after if (data) { with the following lines."

This is the step where things likely went wrong. paste the second block of code after the console.log(data); line instead of replacing

it.  

Go to your housingMap.js file and ensure it looks exactly like the final version provided in the instructions. This is the complete, correct code:

import { LightningElement, wire } from "lwc";
import getHouses from "@salesforce/apex/HouseService.getRecords";
export default class HousingMap extends LightningElement {
    mapMarkers;
    error;
    @wire(getHouses)
    wiredHouses({ error, data }) {
        if (data) {
         // Use JavaScript Map function to transform the Apex method response wired to the component into the format required by lightning-map
          this.mapMarkers = data.map((element) => {
                return {
                    location: {
                        Street: element.Address__c,
                        City: element.City__c,
                        State: element.State__c
                    },
                    title: element.Name
                };
            });
            this.error = undefined;
        } else if (error) {
            this.error = error;
            this.mapMarkers = undefined;
        }
    }
}

save changes and deploy make sure your problems tab shouldn't have any errors. Which means deployment successful.

Hi Nicolas. What helped me was restarting from the previous trail as I found I was pointing to the wrong org. I finally went back and started from scratch which is the module "

where

you "Create a Project". Doing this helped get through this challenge.

The "Your Agent has an error" message in Agentforce Builder during Preview typically indicates a configuration or setup issue. Here are the most common causes and fixes:

Steps to troubleshoot: 

1. Check Einstein User Licenses: Go to Setup [arrow] Users [arrow] Permission Sets. Ensure both the "Einstein Agent (Einstein)" and "Einstein User (Einstein)" permission sets are assigned to your user.
2. Verify the Agent Configuration: In Agentforce Builder, click on your agent and check: (a) the Agent User profile is set correctly, (b) at least one Topic is configured and active, and (c) all Actions within the Topic have valid Flow/Apex references.
3. Check Agent Status: The agent must be in Active state, not Draft. Click the toggle to activate if needed.
4. Review System Prompt: If the System Prompt has formatting issues or references undefined variables, it can cause preview errors.
5. Try a different browser / incognito mode: Sometimes cached state causes issues in preview.
6. Reset Trailhead Playground: If this is a badge challenge, try getting a fresh org from the challenge page and starting over.

If the error persists after these checks, try saving the agent, refreshing the page, and previewing again. You can also check the Setup [arrow] Event Log Files for any AGENTFORCE_ERROR entries.
