The `function_name` column tells you exactly what path was requested, while `cause` indicates whether the platform rejected it or your code returned the 404.
Depending on the output, you can use this table to find the appropriate debugging section:
| Cause | Go to |
|---|---|
| `app_level_error` | [Your function returned a 404](#your-function-returned-a-404) |
| `unrecognized_function` | [Unrecognized function](#unrecognized-function) |
| Cause | Go to |

| `app_level_error` | [Your function returned a 404](#your-function-returned-a-404) |
| `unrecognized_function` | [Unrecognized function](#unrecognized-function) |
