If Monetate detects an issue while processing a file upload, one of the following error messages appears.
| Error Type | Description |
|---|---|
| Wrong File Type | The catalog file is in an unsupported file format. |
| Improper File Encoding | The file doesn't use UTF-8 encoding and must be reformatted. |
| This field is required and may not be null | Each row in the file must contain a value for each required attribute. |
| Missing Column Headers | The file is missing one or more column headers provided in the schema. Column headers must match in both files. |
| Extra Columns Provided | The file contains columns that are not in the schema. Columns in both files must match. |
| Duplicate Column Headers | One or more column headers appear more than once in the catalog file, so you must remove the duplicates. |
| Row Value Doesn't Match Its Data Type | The data in a row doesn't match the expected data type. |
| Unknown NaN Field on Line 1 | Line 1 ends with a comma, which indicates that another field should appear after the comma, but no text is present. The result is a NaN (not a number) error. Remove the comma and then process the file again. |
| System Error | Monetate had an unexpected error while processing the file. Submit a support ticket using the Monetate Technical Support portal (support.monetate.com) to resolve the issue. |
