What should I do if I encounter errors while listing a product?

If you encounter an error while listing a product, first check the exact error message and apply the matching fix below.


Common fixes


1. Reauthorize the sales channel token

If the listing or sync action returns an error, reauthorize the affected sales channel first.


Steps:

  1. Go to Settings > Sales Channel.
  2. Open Authorized Channel or Unauthorized Channel.
  3. Select the affected store.
  4. Click ....
  5. Click Reauthorize Shopee token or the relevant reauthorize option for the channel.


After reauthorizing, try the listing or sync action again.


This is useful when:

  • syncing back Shopee promotions returns an error
  • Lazada product upload shows API validation errors
  • a newly added marketplace requirement is not supported by the current token yet


Reauthorizing does not require you to redo inventory linking or other existing settings.


2. Sync back marketplace promotions before editing the product

If a promotion or discount was created directly in Shopee, sync it back to SiteGiant before editing the product.


Steps:

  1. Go to Apps > Marketplaces.
  2. Open Shopee Promotion Listing.
  3. Click Sync back promotion.


After the promotion is synced, return to the product listing and continue editing.


3. Complete all required variant SKU information

If the system shows that mandatory information is missing even though the product details were filled in, check the SKU field for every variant.


For variant products, the SKU column cannot be left blank.


If you currently do not have stock for some variants:

  • combine Variant 1 and Variant 2 into one variant if you do not want to keep a two-level variant setup, or
  • enter the SKU, complete inventory linking, and set the stock to 0 or out of stock for those variants


If you updated or added variants in Lazada or Shopee Seller Center, sync back the product in SiteGiant and perform inventory linking again.


4. Check category and variant limitations

Some categories do not allow variants or only allow specific variant fields. If your listing fails, check whether the selected category supports the variant structure you are using.


You can either:

  • change to a suitable category, or
  • remove the extra option or variant setup


For some Lazada categories, specific variant fields are compulsory. For example, the category may require both Color Family and Size / Units. If you use only one variant, the listing will return an error.


What to do:

  • review the required variant fields in Lazada Seller Center
  • use all compulsory variant levels required by the category
  • do not replace them with other custom variation types if the category does not allow it
  • if is customized is selected, untick it unless the product really requires that setting


5. Use the required variation name

For some platform errors, changing the variation name to the required platform field can resolve the issue.


Examples:

  • for a Lazada upload error, changing the variation name to Color Family allowed the product to upload successfully
  • remove values that were added incorrectly at parent SKU level if they conflict with the required variant setup


6. Check platform-side product status

If the error says the product is not supported to list in the designated sales platform, check the product status in the marketplace seller center.


Examples:

  • in TikTok Seller Center, a product in frozen status cannot be updated
  • if the product does not appear in seller center, create or verify it there first


7. Review shipping or logistics restrictions

Some listing errors are caused by enabled logistics settings.


Example:

  • if SPX Express is enabled, the product dimensions cannot exceed 40 cm on each side


Check the shipping requirements for the enabled delivery method and update the product dimensions if needed.


If the product fails to list because of GTIN settings:

  • try reauthorizing the Shopee store first
  • then retry the listing with either No GTIN selected or a GTIN filled in, depending on the product requirement


If the product requires GTIN, do not select No GTIN and fill in the GTIN field instead.


If the issue continues

If the error still appears after checking the points above, verify:

  • which store and platform the error belongs to
  • which product is affected
  • what action triggers the error, such as publish, save, sync back product, or sync back promotion


Then retry the action after updating the affected product information or channel authorization.
