Not rendering in shiny.

For example:

library(shiny)
library(shinydashboard)
library(mapview)

ui <- dashboardPage(
  dashboardHeader(title = "test"),
  dashboardSidebar(),
  dashboardBody(
    mapviewOutput("map")
  )
)

server <- function(input, output) {
  output$map <- renderMapview({
    mapview(breweries)
  })
}

shinyApp(ui, server)

Produces:

Error in exprToQuo(expr, env, quoted = TRUE) : Don't know how to convert 'leaflet' to a function; a quosure or quoted expression was expected
