+        This error only occurs for posts that contain custom facets. Standard posts without custom facets decode successfully.
+        
+        Debug logs and a snippet of the failing JSON are attached below:
+        ```json
+        {
+          "facets": [
+            {
+              "type": "app.bsky.richtext.facet",
+              "features": [
+                {
+                  "type": "custom",
+                  "value": "example"
+                }
+              ]
+            }
+          ]
+        }
+        ```
+
+        The error in question:
+        ```
+        DecodingError.dataCorrupted(Swift.DecodingError.Context(codingPath: [...], debugDescription: "Invalid facet type", underlyingError: nil))
+        ```
