What should I do if I encounter an error while uploading a product?

Overview


If you encounter an error while uploading a product, first check the exact error message shown in the listing or error tab. The required action depends on the error returned by the marketplace.
If you are not sure of the error displayed, you may directly request the Support Team to check the error by providing the product SKU and store name.


Common product upload errors and how to fix them


1. Invalid or expired channel token

If the error indicates that the access token is invalid, expired, or the channel has been unauthorized, reauthorize the sales channel first.


Examples:

  • The specified access token is invalid or expired
  • Shopee store expired / unauthorized
  • Failed to validate online product count limit from api. Please try again.


What to do:

  1. Go to Settings > Sales Channel.
  2. Select the affected store.
  3. Reauthorize the channel token.
  4. After reauthorization, try uploading or updating the product again.



2. Required specification or variation field is missing

Some upload errors happen because a compulsory specification or variation field is not filled correctly.


Examples:

  • skuId is a mandatory field and must be filled in.
  • The SKU Variation Option is Not Exist
  • Variation name needs to be set as Color Family
  • BIZ_CHECK_MEASURE_PROP_UNIT_IS_EMPTY: The unit of measure property volume cannot be empty!


What to do:

  • Check the product specifications and variation fields.
  • Fill in the compulsory specification values.
  • Use the correct variation name required by the marketplace, such as Color Family when needed.
  • If the error is related to measurement unit or volume, turn on Advance view and fill in the required Unit measurement.
  • If the option selected does not exist in Lazada Seller Center, choose another valid option from the dropdown.


For Lazada skuId errors, update or edit the product from the Lazada platform first, then return to SiteGiant and perform Sync Back Product.
If the sync remains stuck at syncing, click Sync Clear and try Sync Back Product again.

  • If Lazada shows a required sales property error, add the required variation or property based on the category requirement in Lazada Seller Center settings.


For Lazada skuId errors, update or edit the product from the Lazada platform first, then return to SiteGiant and perform Sync Back Product.
If the sync remains stuck at syncing, click Sync Clear and try Sync Back Product again.


If you are adding a new variation to an existing Lazada product and the update shows an error, add the new variation in Lazada Seller Center first, then sync the product back to SiteGiant.
If a product was changed from having variants to no variants, this structure change also needs to be updated in the marketplace first before syncing back.


3. Product category does not support variants

If the selected category does not allow variants or multiple options, the upload will fail.


What to do:

  • Change the product category to one that supports variants, or
  • Remove the extra variant options.


4. Product is under campaign and cannot be edited

Products that are participating in a campaign may not be editable during the campaign period.


5. Variant images are incomplete

If one SKU image is uploaded, all variant SKU images may be required.


Examples:

  • THD_IC_ERR_FC_IC_SKU_IMAGE_001: If you upload a sku picture, then all sku must be uploaded
  • One variant has an image but another variant has a broken or missing image


What to do:

  • Upload images for all variant SKUs.
  • If one variant has an image, make sure the other variants also have valid images.
  • If a variant image is broken, update the image and try syncing again.


6. Images in description are not allowed

Some Shopee stores are not allowed to upload product descriptions with images.

  • THD_IC_ERR_FC_IC_SKU_IMAGE_001: If you upload a sku picture, then all sku must be uploaded


What to do:

  • Upload images for all variant SKUs.


6. Images in description are not allowed

Some Shopee stores are not allowed to upload product descriptions with images.


Example:

  • Parameter is not match the constraints: You are not in the whitelist to add images in description, can only upload plain text


What to do:

  • Contact Shopee customer service to request Description Image Whitelisting, or
  • Remove images from the product description before uploading by turning off the description-with-image option.


7. Product is not supported on the designated sales platform

  • Check the product in the marketplace seller center.
  • Resolve the product status there first, then try syncing or uploading again.


8. Marketplace product is missing or not found

Some upload or update errors happen because the product does not exist in the marketplace seller center, or the seller center product setup does not match the listing setup in SiteGiant.


Examples:

  • Failed to get product quantity on marketplace
  • one product is listed as a single product and another is listed as a variant product using the same linked inventory


What to do:

  • Check whether the affected product is still available in the marketplace seller center.
  • If the product is missing there, create or restore it in the marketplace first.
  • If you are using the same inventory for multiple marketplace listings, make sure the seller center product structure is correct before updating inventory.


9. Duplicate item already exists in seller center

Some marketplace errors mean the product already exists in the seller center, including inactive listings.


Examples:

  • This product duplicates another in your shop. Please modify it or remove the duplicate


What to do:

  • Check the marketplace seller center for an existing listing of the same product.
  • Also check the inactive product list in seller center.
  • If the product already exists in seller center, modify the existing listing or remove the duplicate there.
  • If no duplicate is found, remove the product in SiteGiant and perform Sync Back Product from the seller center to SiteGiant.
  1. Go to Settings > Sales Channel.
  2. Select the affected store.
  3. Click Sync Back Product.


10. Product moved to Error tab or stuck in queue

If products are stuck in queue for a long time or moved to the error tab, retry the sync after checking the error message.


For TikTok, products may be moved to the Error tab due to busy API traffic. May reach out to support to help you move the product to Error tab.


What to do:

  • Check the product under the Error tab.
  • Click on the error to see the exact error message.
  • Fix the issue based on the message, then sync again.


13. Dropdown attribute value is not selected from the list (Error C011 / Error 004)


Lazada requires certain fields — such as brand, category, color family, clothing material, and other specifications — to be selected from the given dropdown list. Typing a custom value or leaving these fields with an invalid entry will cause an error.


Examples:

  • C011: Attribute value that you input is not included in the dropdown list given. Please select from dropdown to avoid error
  • Error 004 when duplicating a product to Lazada platform (often caused by an invalid category or attribute value)


What to do:

  • Click on the error message to identify which field is affected.
  • Go to the product listing and update the flagged field by selecting a valid option from the dropdown list instead of typing manually.
  • For category, re-select the correct category by typing and choosing from the suggestions — do not leave a numeric or invalid value.
  • For brand, choose from the dropdown list. If your brand is not registered in Lazada Seller Center, register it first or temporarily select No Brand.
  • After updating, retry the sync or publish action.


11. Lazada category is locked and cannot be changed

If a Lazada product has already been published, the category is locked and cannot be changed from SiteGiant. The category field in the Lazada listing will appear greyed out.


What to do:

  1. Go to Lazada Seller Center and update or recreate the product with the correct category there.
  2. In SiteGiant, delete the existing listing for this product.
  3. Go to Settings > Sales Channel > Authorized Channel > Lazada > (...) > Sync Back Product to pull the updated listing back into SiteGiant.
  4. Go to Inventory > Inventory Linking, select the Lazada channel store, find the product, update the iSKU in the Draft Listing field, click Confirm > Review Draft Listing > Confirm and Save Listing.


12. Variant image not allowed for size-based variants

If you receive an error such as When size is passed in as a standard category attribute, it is not allowed to set hasImage true, it means Lazada does not allow images to be assigned to size variants, as buyers cannot differentiate sizes by image.


What to do:

  • Remove the images set under the size variant and then click Update.


9. Duplicate SKU or duplicate product URL

When creating products in webstore, duplicate SKU or duplicate product name may trigger errors.

  • Make sure the product SKU is unique.
  • If the product URL is duplicated because the product name is the same, update it under Edit SEO Content.



Extra checks

  • If the error is shown in the error tab, hover your mouse over the error to view the full message.
  • If you updated the product directly in the marketplace seller center, always perform Sync Back Product in SiteGiant after that.


Summary

The fastest way to resolve a product upload error is to identify the exact marketplace error message first, then fix the related token, category, specification, campaign, image, or description issue before uploading again.
