Failed to find geo_point field

[shelbyd]

I have two domain classes that mirror the GeoPoint examples exactly. Yet, in my tests I keep getting the error QueryParsingException[[package] failed to find geo_point field [location]]; } My Building class is

class Building {
  GeoPoint location

  static searchable = {
    location geoPoint: true, component: true
  }
}

I do create the GeoPoint in a beforeValidate block, but it appears to be indexed with the correct data: Indexing class package.Building (index: package , type: building) of id 57 and source {"category":null,"location":{"id":2,"class":"package.GeoPoint","lat":40.15,"lon":5.699999999999999}

I am at a loss for what is going wrong.
