Translation error spanish

Seeing the following in the logs. Looks like a :thing vs. :things confusion in the spanish translation.

Completed 500 Internal Server Error in 140ms (ActiveRecord: 132.0ms)

ActionView::Template::Error (missing interpolation argument :thing in "No hay %{thing} encontraron." ({:things=>"solicitudes"} given)):

    4:   = header
    5:   = :no_things_found.t(things: :requests.t.downcase)
    6: - else
    7:   = header
