Walmart Marketplace upload repair
Walmart error: conditionally required field missing
Applies to: MP_ITEM, MP_MAINTENANCE
What causes this error
Item Spec 5.0 enforces conditional rules: when one field has a specific value, a second field becomes required. Example — if isProp65WarningRequired = 'Yes', then prop65WarningText is required. Sellers hit this when they set the trigger field but leave the dependent one blank.
How to fix it
Option A: fix it manually
- Read the error to find the dependent field (the 'then' field that's missing).
- Identify the trigger field and value that made it required (e.g. isProp65WarningRequired = 'Yes').
- Either supply the dependent field's value, or change the trigger value if it was set in error.
- Re-upload — these rules fire per row, so check every affected SKU.
Option B: fix it automatically
The fixer can identify the exact row and field, but you may need to provide the final seller-specific value.
