-### 11. 404 Errors for Newly Created Records
-- **Problem**: Newly created records sometimes show 404 when immediately updating/linking
+### 11. 404 Errors for Existing Records During Updates
+- **Problem**: Records that exist in the database return 404 when trying to update them
 - **Solution**:
-  - Added retry mechanism with exponential backoff to `updateInterest` function
-  - Will retry up to 3 times with increasing delays (1s, 2s, 3s)
-  - `get-interest-berths` returns empty list instead of throwing error for new records
-  - This handles NocoDB synchronization delays where records need time to propagate
-  - After 3 retries, provides detailed error message explaining possible causes
+  - Added verification step to first try fetching the record before updating
+  - Added retry mechanism with exponential backoff (3 retries with 1s, 2s, 3s delays)
+  - Enhanced logging to show exact URLs, headers, and request bodies
+  - Added Content-Type header to PATCH requests
+  - `get-interest-berths` returns empty list instead of throwing error for 404s
+
+**Investigation Steps Added:**
+1. Verify record exists with GET before attempting PATCH
+2. Log complete request details including URLs and tokens
+3. Retry with exponential backoff in case of timing issues
+
+**If the issue persists:**
+- Check if the NocoDB API token has write permissions
+- Verify the table ID hasn't changed
+- Try updating a different record to see if it's record-specific
+- Check NocoDB logs for more details about the 404 error
