Manual Price Sync Failures: Causes & Troubleshooting Solutions

Set pricing rules once, push instantly — and fix sync failures when they happen.

Note

Manual Price Sync updates hundreds of products in one click — but sometimes, a few variants get left behind. This guide covers the 5 most common sync failures and exactly how to fix them.

Understanding Sync Failures

When you trigger a manual price sync, DSers attempts to update the price for every selected product in your store. If a product fails, it's almost always because:

• The product can't be matched to a valid supplier mapping
• The product no longer exists in your store

Failures fall into 3 categories:

• 1: Unsupported Mapping Types — Products using Advanced Mapping or Bogo mapping.
• 2: No Usable Supplier Found — Missing, invalid, or temporarily unavailable mappings.
• 3: Product Deleted from Store — The product no longer exists on your sales channel.

  

    Category 1: Unsupported Mapping Types   

1. Mapping Type is Multi-Country-Based or Bundle (Advanced Mapping)

What this means: The product uses a legacy mapping type (Country-based) or (Bundle) Advanced Mapping, which are not compatible with manual price sync. Advanced Mapping may involve multiple suppliers per variant, multiple SKUs per supplier, or country-specific supplier assignments.

Solution: Update the price manually in your store backend.

  

    Category 2: No Usable Supplier Found   

2. This Product is Unmapped

What this means: The product was pushed to your store through DSers but was never mapped to a supplier.

Solution:

• Find a supplier and complete the mapping in DSers.

3. No Mapping Suppliers or Supplier is Delisting

What this means: The supplier is temporarily unavailable — typically because the product has been taken down on AliExpress or Alibaba.

Solution:

• Find an alternative supplier and remap.

4. Error: "Sync to Seller is Nil"(PRODUCT_INTERNAL)

error: code = 400 reason = PRODUCT_INTERNAL message = sync to seller is nil

What this means: DSers can't find the corresponding product in your store — the mapping has broken.

Why it happens:

• The supplier changed or removed SKUs.
• The supplier is no longer offering the product.

Solution:

• If the supplier product is still active, remap the product in DSers. If not, find a new supplier and remap.

  

    Category 3: Product Deleted from Store   

5. This Product is Deleted from Seller

What this means: The product has been deleted from your store and no longer exists on your sales channel.

Solution:

• If the product is still in your DSers Import List, re-push it to your store.
• If you no longer need it, delete it from DSers.

  

Next Steps: Re-sync and Prevent Future Failures   

Once you've fixed the root cause, return to Settings > Product Settings > Manually change store products price, select the resolved products, and click Update to retry.

Before re-syncing, check your remaining usage:

• Attempts left → proceed with the sync.
• No attempts left → upgrade your plan for more attempts, or update prices manually in your store backend.

To prevent future failures: monitor your Import List for unmapped or invalid mappings, and remap promptly when suppliers change SKUs or delist products.
