Error Detection & Validation
To prevent catalog corruption and broken product data, the Magento 2 Multi Vendor Mass Upload module includes built-in validation mechanisms before committing products to the database.
Validation & Error Reporting
If an import file contains syntax errors, missing mandatory headers, invalid SKU references, or corrupt image filenames:
- The profiler automatically halts the execution process immediately.
- No invalid or partial product rows are written to the store database.
- Detailed line-by-line error notifications are rendered in the profiler output log.
Common Import Errors & Solutions
| Error Message | Cause | Resolution |
|---|---|---|
SKU Already Exists | SKU matches an existing product in another seller catalog. | Ensure SKUs are unique across all marketplace products. |
Attribute Set Not Found | File header doesn't match selected attribute set. | Select the exact attribute set or use Dataflow Profile mapping. |
Image file does not exist in zip | Image filename referenced in CSV is missing from the ZIP container. | Verify image file names and extensions inside the ZIP folder. |
Invalid Category Path | Category syntax is incorrectly formatted. | Use >> for parent-child paths and , between multiple paths. |
