Could not find content item

Error message

Could not find content item 

What it means

metaWeblog.getRecentPosts requires the contentItemId to reference an existing list (e.g. a Blog). If IContentManager.GetAsync returns null the handler throws 'Could not find content item ' + contentItemId (note the unlocalized string with no closing punctuation).

Solutions

1. Verify the blogId/content item ID in the client config matches an existing Blog content item's ID (copy it from the admin URL)
2. Check you are connecting to the correct tenant/site URL
3. Recreate or republish the blog and update the client

var exists = await contentManager.GetAsync(blogId); if (exists == null) throw new ArgumentException($"Blog '{blogId}' does not exist on this site");

bool IsValidContentItem(ContentItem item) => item != null && !string.IsNullOrEmpty(item.ContentItemId);

try { posts = await handler.MetaWeblogGetRecentPosts(blogId, ...); } catch (InvalidOperationException ex) when (ex.Message.StartsWith("Could not find content item")) { RefreshBlogConfiguration(); }

When it happens

Trigger: Calling getRecentPosts with a blogId that does not match any content item ID, or with a deleted/unpublished-removed item.

Common situations: Mistyped or stale blog ID in blog client configuration; connecting to the wrong tenant/site; content deleted after the client was configured.
