The Slack SDK version

Module Version: slack.api.model: 1.29.2

Java Runtime version

openjdk version "11.0.20.1" 2023-08-24 OpenJDK Runtime Environment (build 11.0.20.1+1-post-Ubuntu-0ubuntu122.04) OpenJDK 64-Bit Server VM (build 11.0.20.1+1-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)

OS info

34~22.04.1-Ubuntu

Steps to reproduce:

(Share the commands to run, source code, and project settings (e.g., pom.xml/build.gradle))

1. I call view.update to show a pop-up modal in slack
2. When I click on Submit button, I want to return a slash message to channel and close the modal automatically
3. Btw, I just can handle the first clause, I can't find out the way to close the modal without clicking on Cancel Button
4. Here is my code:

 private fun main(payload: InteractionPayloads?, userId: String, channelName: String?) {
    if (payload is InteractionPayloads.IViewSubmissionPayload) {
      val SubmissionPayload = payload.payload
       if (blockActionPayload.view.callbackId == SlackButtonConstants.cutoffButton) {
          // return slash message -> this is not related to my question
        }
    } else {
      warn {
        "Error handling submission action due to=$payload"
      }
    }
  }

5. Actually, I don't handle any ViewSubmission in my code, how could I do now.

6. FYI, this is my code to handle ViewUpdateRequest:

   fun viewUpdate(id: String): ViewsUpdateRequest {
   val modalView = View.builder()
     .callbackId(myButton)
     .type("modal")
     .clearOnClose(true)
     .title(
       ViewTitle.builder()
         .type("plain_text")
         .text("Modal")
         .emoji(false)
         .build()
     )
     .submit(
       ViewSubmit.builder()
         .type("plain_text")
         .text("Submit")
         .emoji(false)
         .build()
     )
     .blocks(SlackCommonResponses("Please select an option")
     .build()
   
   return ViewsUpdateRequest.builder()
     .view(modalView)
     .viewId(id)
     .build()
   }

Expected result:

I want to close the modal before send slash message to slack

Actual result:

Hi @RedHoes, thanks for asking the question.

Btw, I just can handle the first clause, I can't find out the way to close the modal without clicking on Cancel Button

Unfortunately, there is no way to do this. Only your end-users can close the modal by clicking either x on the top or Cancel button.

I want to close the modal before send slash message to slack

To send your message asynchronously, you can use app.executorService().submit() to run the logic. To ensure the message is sent out a while after closing the modal dialog, you may want to have Thread.sleep(ms) in the code executed by the ExecutorService. Refer to https://slack.dev/java-slack-sdk/guides/bolt-basics for the code snippets.

I hope this helps.

Thanks for your answer, but anytime I click on the Submit button, this message appears, how to avoid it: We had some trouble connecting. Try again?

Could you double-check if your app code has an app.viewSubmission listener for the callback_id plus you’ve set a valid Request URL in the Interactivity & Shortcuts section on your api.slack.com/apps site?

[RedHoes]

I haven't set up the app.viewSubmission listener yet, but I wonder if I can setup the listener through my slack bot, because all the actions I manage in Slack is from this slackbot. Below is how I setup the slack bot private val botClient: MethodsClient = Slack.getInstance().methods(config.slack.botToken)

[seratch]

The Slack instance provides only we api wrapper methods (e.g., chat.postMessage, views.open), so it does not support handlers for incoming requests from Slack. To handle those, you need to use App instance with valid configuration on api.slack.com site instead.

Thanks so much, I could resolve the issues
