Just wrapping up my experience with

Challenge 3 — thought the details might be useful.

Initially, I encountered the error:

This was resolved by adding @AuraEnabled, as per the documentation in Exercise 1: Invoke Prompt Templates from Apex and Lightning Web Components

. 

However, after completing the Apex implementation, the challenge still failed with a generic error asking to contact Trailhead support, despite everything looking correct.

After some experimentation, I decided to remove @AuraEnabled

entirely since LWC wasn’t required for this challenge, and that did the trick. 

✅

Challenge Passed Successfully

So the final fix was to not use @AuraEnabled at all, even though it resolved one of the initial errors.

Sharing Apex code, in case others run into the same confusing behavior.

public class GuestReviewRatingCalculator {
    public Experience__c generateRatingParams(String experienceId){
        System.debug(experienceId);
        Map<String, String> experience = new Map<String, String>();
        experience.put('id', experienceId);
        ConnectApi.WrappedValue experienceValue = new ConnectApi.WrappedValue();
        experienceValue.value = experience;
        Map<String, ConnectApi.WrappedValue> inputParams = new Map<String, ConnectApi.WrappedValue>();
        // List<Experience__c> exps =  [SELECT Id, Name, Communication__c, Value__c, Accuracy__c FROM Experience__c where Id=:experienceId];
        //TO-DO Configure Prompt Template Input API Name(Input:experience)
        inputParams.put('Input:experience', experienceValue);
        // Configure invocation parameters
        ConnectApi.EinsteinPromptTemplateGenerationsInput executeTemplateInput = new ConnectApi.EinsteinPromptTemplateGenerationsInput();
        executeTemplateInput.additionalConfig = new ConnectApi.EinsteinLlmAdditionalConfigInput();
        executeTemplateInput.additionalConfig.applicationName = 'PromptBuilderPreview';
        executeTemplateInput.isPreview = false;
        executeTemplateInput.inputParams = inputParams;
        try {
            //TO-DO Call the service generateMessagesForPromptTemplate to generate response by specifying the prompt template API name and input parameters

                executeTemplateInput
            );
            //TO-DO Extract the response text from generations property
            ConnectApi.EinsteinLLMGenerationItemOutput response = generationsOutput.generations[0];    
            //Deserialize the response 
            Map<String, Object> jsonMap = (Map<String, Object>) JSON.deserializeUntyped(response.text);
            Decimal accuracy = jsonMap.containsKey('Accuracy') ? (Decimal) jsonMap.get('Accuracy') : 0;
            Decimal value = jsonMap.containsKey('Value') ? (Decimal) jsonMap.get('Value') : 0;
            Decimal communication = jsonMap.containsKey('Communication') ? (Decimal) jsonMap.get('Communication') : 0;
            //Update the Experience record with the deserialized response
            Experience__c exp = new Experience__c(Id=experienceId, Value__c =value,  Accuracy__c=accuracy, Communication__c = communication);
            update exp;
            return exp;
        } catch (Exception e){
            System.debug(e.getMessage());
            throw e;

I did the first step of the instructions mentioned below and it worked!  

Here are some steps and resources to help resolve the issues you're facing with the Agentforce setup and the Coral app error:

1. Connecting Playground and Developer Agent

• Ensure that the Salesforce CRM connection is reactivated in the sandbox environment. Follow these steps:
  1. Go to Setup > Einstein Setup and toggle on Einstein.
  2. Navigate to Setup > Agentforce Agents and toggle on Agentforce.
  3. Ensure Einstein Bot is turned on in Setup > Einstein Bot.
  4. Verify that Data Cloud Setup Home is enabled.
• If you encounter an error indicating that agents are still being provisioned, toggle the Agentforce setting and try again.
• Reference: Agentforce Activation in Sandbox1

2. Error in Coral App

• If the Coral app displays an error like "Something went wrong. Refresh conversation and try again," ensure the following:
  1. Check that Lightning Experience users have the correct permissions for the specific agent.
  2. Navigate to Setup > Permission Sets or Profiles.
  3. Select the relevant Permission Set or Profile and click Enabled Agent Access.
  4. Edit the Enabled Agent Access section, select the agent(s) users should have access to, and move them to the Enabled Agents list.
  5. Save changes, refresh the page, and verify if the error is resolved.
• Note: If the issue persists, contact Salesforce Support for further assistance.
• Reference: Manage Employee Agent Access2

3. Testing the Coral Cloud Experience Agent

• To test the Coral Cloud Experience Agent:
  1. Activate the Coral Cloud Experience Agent.
  2. Publish the ESA Web Deployment:
     • Go to Setup Quick Find > Embedded Service Deployments.
     • Select ESA Web Deployment and click Publish.
  3. Activate Messaging:
     • Go to Setup Quick Find > Messaging Settings and toggle Messaging to On.
  4. Publish the Experience Cloud Site:
     • Go to Setup Quick Find > All Sites.
     • Select Builder next to the coral-cloud site and click Publish.
  5. Configure the Flow:
     • Update the Service Channel to Messaging.
     • Set the Route To field to Agentforce Service Agent.
     • Save as a new version and activate the flow.
  6. Add the Coral Cloud Experience Agent to the coral-cloud site:
     • Add the Embedded Messaging component to the site and publish the changes.
  7. Enable standard external profiles login:
     • Go to Setup Quick Find > Digital Experience | Settings.
     • Select the checkbox Allow using standard external profiles for self-registration, user creation, and login, and save.

4. Additional Tips

• Before adding the Embedded Messaging component to the coral-cloud site, ensure the site and ESA Web Deployment are published.
• If you encounter the error "Copilot Version cannot be activated," toggle the Agentforce setting and try again.
