Question:
Why is contentText not returning blog posts content? api reference getPost

Product:
Wix Editor

What are you trying to achieve:
I want to get blog posts in plain text onto a webpage.

What have you already tried:
I created a backend JSW file with this code:

import { posts } from 'wix-blog-backend';

export async function getAllPostsContent() {
  try {
    const result = await posts.listPosts();
    const postIds = result.posts.map(post => post._id);
    return postIds;
  } catch (error) {
    console.error('Error fetching posts:', error);
    throw error;
  }
}

export async function getPostContent(postId) {
  try {
    const options = {
      fieldsets: ['URL', 'CONTENT_TEXT'] // Specify the fieldsets to include 'CONTENT_TEXT'
    };
    const result = await posts.getPost(postId, options);
    const contentText = result?.post?.contentText; // Check if contentText is defined
    if (contentText !== undefined && contentText.trim() !== '') {
      console.log(`Content text found for post ${postId}:`, contentText); // Log contentText
      return contentText; // Return contentText if it's not empty
    } else {
      console.warn(`Content text not found or empty for post ${postId}`);
      return null; // Return null to indicate that contentText is not available
    }
  } catch (error) {
    console.error(`Error fetching content for post ${postId}:`, error);
    throw error;
  }
}

and the frontend code

import { getAllPostsContent, getPostContent } from 'backend/getBlogPosts'; // Importing the functions from the backend JSW file

// Function to fetch all posts content IDs from the backend
async function fetchAllPostsContentFromBackend() {
  try {
    const postIds = await getAllPostsContent();
    console.log('All posts content IDs:', postIds);

    // Fetch content for each post
    for (const postId of postIds) {
      try {
        const contentText = await getPostContent(postId);
        if (contentText !== null) { // Check if contentText is not null
          console.log(`Content text for post ${postId}:`, contentText);
          // Do something with the fetched content text
        } else {
          console.warn(`Content text not found or empty for post ${postId}`);
        }
      } catch (error) {
        console.error(`Error fetching content for post ${postId}:`, error);
      }
    }
  } catch (error) {
    console.error('Error fetching all posts content from backend:', error);
  }
}

// Call the function to fetch all posts content IDs from the backend
fetchAllPostsContentFromBackend();

Additional information:
however, the console log preview returns the following error message for every blog post ID - Content text not found or empty for post [ID]
