If you are receiving the error "The filters should be facet filters", this is being caused by filters being returned with numerical operators such as =, <, >, <= and >=. This is likely a result of a known issue with the
rangeInput widgets used in InstantSearch.js.
By default, the
rangeInput widgets use the
sendEvent function with
numericFilters, which results in this error.
This won't have any impact on your analytics or related features, but these events will not be recorded, and for the moment, it is not possible to use analytics events with these widgets.
