triangle-exclamationHow to solve common Amazon errors

Good to know

Listings with errors in Channable may still be accepted and listed by Amazon. To check which items are successfully listed on Amazon, review the Overview tab in the Result step.

Feedback: This page shows all current errors related to your listing based on the previous runs of your API. These errors may result from:

  • Manual data entry on Amazon

  • Another third-party tool

  • A previous run of your API in Channable


Error types

Understand the error types:

Errors indicate an issue occurred which prevented the submission from processing (e.g. a validation error).

Submission errors

Submission errors happen when Amazon encounters issues processing your product data after you send your listings.

circle-exclamation

Listing errors

Listing state errors are additional errors requested from Amazon to make sure you have all information you need to go live and optimize your listing. Because we pull all possible errors, some listing state errors aren’t relevant to and can't be resolved within Channable.

circle-info

Note: If you notice a product with a listing error is updating as it should on Amazon, you can ignore the error, but fixing listing state errors can improve your listing quality.

WARNING

Indicates an issue occurred that should be reviewed but hasn't prevented the submission from processing.

- In the Build step, check any fields marked as Required by marketplace. Click the + Add button to view fields out of view. - Map the correct inventory file template for your product category. - Verify the Category (Item Type Keyword) field. - Update and resubmit your data.

Product ID Doesn't Match Any ASINs

chevron-rightSubmission error 99022 / 99220: Mismatched attribute declarationshashtag

Error description:

These errors indicate a static type/unit attribute (e.g. “ean” for ID, “EUR” for currency) was declared, but the value for a directly related attribute is missing, empty, or invalid.

In Amazon’s system, if you include a type or unit attribute, it expects to receive a valid value for other associated attributes. When this doesn’t happen, Amazon rejects the data, triggering these errors.

Common scenarios (Shared attributes):

  • External product ID: Product type is set as a static field (‘ean’, ‘gtin’, or ‘upc’) but ID is mapped to a field that is either empty or occasionally empty (e.g. some, but not all products have a value in this field).

  • Offer information: Currency is set as a static field (e.g. ‘GBP’, ‘EUR’), but Price is mapped to an empty field.

Common causes:

  • Missing source data: The “value” field (e.g. field containing product eans, field containing prices) is missing values or completely empty, but the static field is declared.

  • Conflicting rule: You’ve set up a rule in Channable that clears the “value” field under certain conditions (e.g. IF ASIN isn’t empty, take “ean” and set to value [blank]), but didn’t account for related static attributes.

Solution:

Create a dynamic project field to replace the static field for the unit/type attribute. This field should be set to only declare a type/unit attribute to Amazon when its corresponding attribute contains valid data.

  1. Identify the attribute:

    • In the Feedback step of [your Amazon channel], click on the error message to see which attribute is affected. Note the type/unit field (e.g. “Type” in External Product ID section) and its corresponding value (e.g. “ID in External Product ID section).

  2. Create a new project field for the unit/type attribute

    • Go to the Rules step.

    • Click to add a project field.

    • For Name, give your field a descriptive name (e.g. “id_type”)

    • For Type, select Text.

    • Click Save.

  3. Build the dynamic logic for your new field:

    • Click + Create rule.

    • Create a rule that sets the values in your new project field based on its corresponding value field.

    • Click Save to save your rule.

Example rule (product ID):

In this example, the new project field is id_type, and the ean field contains product ids.

  • IF: ean isn’t empty

  • THEN: take id_type and set to value “ean”

  • ELSE: take id_type and set to value “ ” (leave this blank)

  1. Update the Build step.

    • Return to the Build step

    • Locate the type/unit attribute causing the error.

    • Replace the static field with your new dynamic project field.

    • Click Save.

Re-run your channel.

chevron-rightError 99001 / 99010 / 90057: Issues with required attributeshashtag

Description: These errors stem from problems with required values in attributes in your product's category and the build step. They indicate required attributes (like ID type, item ID, stock, price, title, description, sale attributes, parent-child attributes) are filled incorrectly or left blank.

Solution:

  1. In your Amazon API setup, go to Attributes and select your category to view all attributes. Incorrectly filled attributes are highlighted in red. Adjust their values to match the listed “Possible Values”.

  2. In the Build section of your API, check all required attributes (marked with *) and ensure they are filled.

For more details on which value is wrong for which attribute, download the processing report from Amazon Seller Central. Steps are explained here.

chevron-rightError 99038: Error due to invalid characters in the descriptionhashtag

Description: Your description contains at least one disallowed character or HTML tag. Not all HTML tags are valid in Amazon descriptions and Amazon does not provide a definitive list of allowed tags.

Solution: Set up a rule within your API to remove HTML from your description field (if non-essential) or to strip specific tags. Use trial and error to identify and remove the forbidden tags Amazon accepts the description.

chevron-rightShipping Status Not Updating: Order status remains "unshipped" on Amazonhashtag

Description: Channable sends a shipping update to Amazon but the order status remains "unshipped". Usually this occurs when the delivery service has not been properly configured in the order connection.

Solution:

  • Configure transporters for the delivery services in Channable. Amazon requires selecting a specific delivery service (e.g. DHL, DHL Express, DHL ECOMMERCE INTERNATIONAL STANDARD).

  • Verify the chosen delivery service is available in your Amazon Seller account and select the matching service in Channable’s transporter settings.

Consult the provider or switch to a different host (e.g. S3), then resubmit.

Unknown Host Exception

Invalid URL or client-server configuration issue
