Walmart 5.0: Prop 65 Warning Text required when warning flag is Yes

Applies to: MP_ITEM, MP_MAINTENANCE

What causes this error

Item Spec 5.0 introduced isProp65WarningRequired as a new attribute. When it's set to 'Yes', prop65WarningText becomes conditionally required (max 5,000 chars). Sellers migrating from 4.x often set the flag without supplying the text.

How to fix it

Option A: fix it manually

  1. For every SKU where isProp65WarningRequired = 'Yes', supply prop65WarningText.
  2. Keep the warning text under 5,000 characters.
  3. If a product needs no Prop 65 warning, set the flag to 'No' rather than leaving it blank.
  4. Re-upload after both fields are consistent per row.

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.
