reset checkbox group with action button

[osrs]

i have a checkbox group in my shiny dashboard body

checkboxGroupInput("dbr", selected = NULL,
                                                      h4("Select a box"),
                                                      c(
                                                          "Low" = "Low",
                                                          "Medium" = "Medium",
                                                          "High" = "High",
                                                          "Critical" = "Critical"
                                                      # End check list 
                                                      ), 
                                                      # End check group
                                                      
                                   ),

i also have an action button that I'm using as a reset button for checkbox items on the page

actionButton("reset_artifact_entry", label = "Reset")

in the server section of the code i have a call for reset

server <- function(input, output, session)

    # Rest button for artifact entry page
    observeEvent(input$reset_artifact_entry, {
        updateCheckboxGroupInput(session, "dbr", selected = NULL)
        
    })

i don't get any errors when the code runs, but nothing happens when i click the button either -
I've looked all over stackoverflow and wherever i could to find the solution to this...
I'm sure its in the way i have it set up but i can't seem to find where

cheers ~!

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.2…
