- Remove the query string component from the redirect target URL
This error occurs when there are different types of list items (for example, IP addresses, hostnames, and URL redirects) in a single operation to add items to a list. The error may occur for an IP list, a hostname list, or a Bulk Redirect List.
Remove the list items that do not apply to the list type. This means:
- Removing IP addresses from a request to add items to a Bulk Redirect List
- Removing URL redirects from a request to add items to an IP list
This error occurs when you are adding items to a list (either IP list, hostname list, or Bulk Redirect List) and the list items are incompatible with the list type.
Make sure you are adding the items to the correct list:
- Custom lists with IP addresses (IP lists) can only contain IP addresses as list items
- Custom lists with hostnames can only contain hostnames as list items
- Bulk Redirect Lists can only contain URL redirects as list items
This error occurs when you have more than the maximum number of URL redirects with the same source URL path across all Bulk Redirect Lists in your account, regardless of the URL redirect domain.

Refer to URL redirect parameters for more information on the current limits.
