googleAnalyticsR package cannot coerce type 'closure' to vector of type 'character'

When I run the following code I see no error and the Shiny app renders and performs as expected.

library(shiny)
library(googleAuthR)

gar_set_client(scopes = c("htps://www.googleapis.com/auth/analytics.readonly"))

library(googleAnalyticsR)

ui <- fluidPage(
  googleAuth_jsUI("auth")
  )

server <- function(input, output, session) {
}

shinyApp(ui = ui, server = server)

However, when I run a later iteration with the addition of the auth module I get a coercion error

library(shiny)
    library(googleAuthR)

    gar_set_client(scopes = c("htps://www.googleapis.com/auth/analytics.readonly"))

    library(googleAnalyticsR)

    ui <- fluidPage(
      googleAuth_jsUI("auth")
      )

    server <- function(input, output, session) {

    auth <- callModule(gar_auth_js, "auth")


    }

ERROR:

Error in as.character(function (input, output, session, message = "Authenticate with your Google account")  :

Error is due to deprecation of: auth <- callModule(gar_auth_js, "auth")

Instead the following must be used. auth <- callModule(googleAuth_js, "auth")
