Why am I getting "The Search API returned an error invalid numeric attribute(attribute name), attribute not specified in numericAttributesForFiltering setting in the query suggestion index?

This error can appear if there are any rules you have configured in the suggestion index that attempt to return hits on attributes that don't exist within the suggestion index.

To troubleshoot in this situation, you can conduct the following steps:

1. Disable rules from the "advanced search" section under the "Add query parameter"
2. Then, search the suggestion term that returns the error message again
3. At this point, the search should no longer produce the error and return hits as expected

Note that if you have multiple suggestion indexes, consider doing a comparison with the other suggestion indexes to check if there are any changes in the default suggestion index settings. You may need to revert the changes if this is applicable.
