# How 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. {% hint style="warning" %} **Important:** If one of your products has a submission error, it can have a cascading effect and prevent other products from processing. Prioritize fixing submission errors before addressing other errors. {% endhint %} **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. {% hint style="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. {% endhint %} **WARNING** Indicates an issue occurred that should be reviewed but hasn't prevented the submission from processing. *** ## Solve in Channable

Submission error 99022 / 99220: Mismatched attribute declarations **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) 4. **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**.
Error 99001 / 99010 / 90057: Issues with required attributes **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](/list-advertise/amazon/amazon-troubleshooter.md).
Error 99038: Error due to invalid characters in the description **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.
Shipping Status Not Updating: Order status remains "unshipped" on Amazon **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. For more details on configuring transporter settings, refer to [this article](https://channable-test.gitbook.io/channable-test-docs/list-advertise/orders/configuring-transporter-settings-for-order-connections). If the delivery service does not appear in Channable, [contact Support](https://channable-test.gitbook.io/channable-test-docs/contact-support).
Channable Error: We were unauthorized to access Amazon **Description:**\ This error indicates Channable couldn't establish a connection with Amazon for your account. **Solution:** | Cause for the error | Solution | | --------------------------------- | ----------------------------------------------------------------------------------------------------------- | | Wrong API key or Amazon seller ID | Go to your Amazon Seller Central account to get correct credentials or generate a new API token. | | Payment method issue | In Seller Central navigate to **Settings → Account Info → Payment Information** and update payment details. | {% hint style="info" %} Note: Refresh your payment method multiple times and proactively check if Amazon requires account verification. {% endhint %} Subaccounts: If you use a main Amazon account with subaccounts, all settings must be set up separately, including the payment method. Check whether the account needs verification — subaccounts may not receive notifications.
