-### Technical Task: Fix Facebook Graph API Image Upload (403 Forbidden)
-
-**Objective:**
-Modify `FacebookPostingService.java` to resolve the `403 Forbidden` error caused by using a User Access Token for image uploads. Implement a mechanism to automatically exchange the User Token for a Page Access Token before attempting the upload.
-
-**Context:**
-The application is currently failing with this error:
-`(#200) This endpoint is deprecated since the required permission publish_actions is deprecated`
-
-This happens because we are trying to post to `/{userId}/photos` or using a User Token on a Page endpoint. Facebook requires a **Page Access Token** to post content. The user has valid permissions (`pages_read_engagement`, `pages_manage_posts`), but the code is not fetching the correct token type.
-
-**Required Changes:**
-
-1.  **Implement Token Exchange Method:**
-    Create a helper method `getPageCredentials(String userAccessToken)` that:
-
-    - Calls `GET /me/accounts?access_token={userToken}`.
-    - Parses the JSON response to find the first available Page.
-    - Extracts the `id` (Page ID) and `access_token` (Page Token).
-    - Returns these credentials.
-
-2.  **Update `postToFacebookWithImage`:**
-
-    - Remove the logic that calls `getPageId` (which only returns the User ID or Page ID without a token).
-    - Instead, call the new `getPageCredentials`.
-    - Use the returned **Page Token** and **Page ID** for the subsequent `/photos` upload request.
-
-3.  **Refactor `publishPostWithImage`:**
-
-    - Ensure the `access_token` query parameter uses the **Page Token**, not the User Token passed into the service originally.
-    - Keep the `ByteArrayResource` filename override (critical for multipart uploads).
-
-**Code Reference (Implementation Details):**
-
-Please replace the existing logic in `FacebookPostingService.java` with the following flow:
-
-```java
-// 1. New Helper Class
-private static class PageCredentials {
-    String pageId;
-    String pageToken;
-    public PageCredentials(String pageId, String pageToken) {
-        this.pageId = pageId;
-        this.pageToken = pageToken;
-    }
-}
-
-// 2. New Method to fetch Page Token
-private PageCredentials getPageCredentials(String userAccessToken) {
-    // Call https://graph.facebook.com/v18.0/me/accounts
-    // Return the first page found in the "data" array
-}
-
-// 3. Updated Main Method
-public String postToFacebookWithImage(String userAccessToken, ...) {
-    // Step A: Exchange tokens
-    PageCredentials creds = getPageCredentials(userAccessToken);
-
-    // Step B: Upload using creds.pageToken and creds.pageId
-    return publishPostWithImage(creds.pageToken, creds.pageId, ...);
-}
-```
-
-**Acceptance Criteria:**
-
-- The service must successfully fetch a Page Access Token using the provided User Access Token.
-- The image upload request must target `/{pageId}/photos`.
-- The upload request must use the **Page Access Token**.
-- The `403 Forbidden` error regarding `publish_actions` must no longer appear.
