Understanding the Issue

The error message indicates that the community user lacks the necessary permissions to access the Prompt Template feature. This is because the Prompt Template User permission set only provides access to the Prompt Template feature, but does not grant the necessary Data Cloud permissions.

The root cause of the issue is the missing Data Cloud permission set, which is required to access the Prompt Template feature from a community user.

Step-by-Step Solution

To resolve the issue, follow these steps:

First, assign the Prompt Template User permission set to the community user. This will provide access to the Prompt Template feature.

Next, assign the Data Cloud permission set to the community user. This will grant the necessary Data Cloud permissions to access the Prompt Template feature.

Finally, ensure that the Apex code is executed with the necessary privileges by using the without sharing keyword.

ApexExample.cls

public without sharing class ApexExample {    public static void callPromptTemplate() {        ConnectApi.EinsteinLLM.generateMessagesForPromptTemplate('templateId', new ConnectApi.EinsteinPromptTemplateGenerationsInput());    }}

Best Practices

To avoid similar issues in the future, ensure that community users have the necessary permission sets and that Apex code is executed with the necessary privileges.

Heads up: always test your code in a development environment before deploying it to production.
