Getting We had some trouble connecting. Try again? after updating a view. Using aws lambda.
Below code will open a comment modal.
// Handle selection of a pending task in the static select
app.action(
{ type: "block_actions", action_id: /^pending_task_action_(\d+)$/ },
async ({ ack, body, client }) => {
await ack();
const selectedOption = body.actions[0].selected_option.value;
const selectedApplicationId = body.actions[0].block_id;
const userEmail = body.user.name + "@mdsol.com";
// Open a modal with a text input for reason
await client.views.open({
trigger_id: body.trigger_id,
view: {
type: "modal",
callback_id: "reason_modal",
private_metadata: JSON.stringify({
selectedOption,
selectedApplicationId,
userEmail
}),
title: {
type: "plain_text",
text: ":wave: Please comment ",
},
blocks: [
{
type: "input",
block_id: "reason_input",
element: {
type: "plain_text_input",
action_id: "reason",
multiline: true,
},
label: {
type: "plain_text",
text: "Please provide comment for your action:",
},
},
],
submit: {
type: "plain_text",
text: "Submit",
},
},
});
}
);
And After comment we will update the existing view with
// Handle submission of the reason modal
app.view('reason_modal', async ({ ack, body, view, client }) => {
await ack()
const viewId = view.id;
// Open a quick loading modal
await client.views.update({
view_id: viewId,
"response_action": "update",
view: {
type: "modal",
title: {
type: "plain_text",
text: ":man-biking:Processing..",
},
blocks: [
{
type: "section",
text: {
type: "plain_text",
text: ":hourglass_flowing_sand: Please wait while we process your request...",
},
},
],
},
});
**
But I am getting an error as We had some trouble connecting. Try again? after submitting the comment.

Hi @tusharwagh-mdsol, thanks for asking the question!
When you want to update the submitted modal in app.view listeners, you can use await ack({ response_action: "update", view: view}) instead of views.update API call. Please refer to https://slack.dev/bolt-js/concepts#view-submissions for more details.
Hi @seratch Thanks for the quick response. So basically i am using aws lambda for hosting my bolt application using JS.
In above code when we submit the comments i want to display processing modal and after that the modal should get updated with another message as this task is completed but here task completion will take some time to complete because we have some api calls as well and also after task completion I have to refresh the homeview as well to remove the completed task.
Can you please suggest best way to do this ?
below is the full code for the same.
// Handle submission of the reason modal
app.view('reason_modal', async ({ ack, body, view, client }) => {

bolt-python's lazy listeners could be the best solution for your use case: https://slack.dev/bolt-python/concepts#lazy-listeners However, unfortunately the same functionality does not exist in bolt-js due to its design restrictions. Also, we don't have plans to enhance bolt-js for the need.
If we want to write your app using bolt-js + AWS Lambda, the only suggestion I can give is to have a queue for delegating the time-consuming task to a different Lambda function. You can store the event payload and view_id etc. into the queue message. With that, the async task worker function can update the end-user once the task completes.
I hope this helps. Is everyting clear now? If yes, would you mind closing this?
