views.update method gives `not_found` sometimes

[kranti-rh]

I'm using views.update very often. Sometimes it gives not_found which means view_id or external_id doesn't exist. But when I saw logs view_id for the view I'm gonna update is there. What else could be the reason for this issue. Any help much appreciated.

Hi @kranti-rh! 👋 This certainly seems unexpected since you're using the view_id that appears in your logs, so I'm interested if something else might be going on.

I tried to reproduce this error myself with a race condition and calling views.update immediately after creating the modal, but didn't run into this problem. Could you share a bit more about how you're calling views.update?

• How often is this error occurring? Does it mostly happen in any specific circumstance?
• Are you using the Bolt for Java or calling the Slack API Client directly?
• Is the call to views.update happening immediately or after some delay?

Hi @zimeg, Thank you for your response. Definitely, that might be something else.

My use case is to open a modal by clicking a button from a chat message. So, when the button is clicked, a BlockAction triggers. Then using the triggerId from BlockActionRequest opens( using slack.methods().viewsOpen(...) ) a loading modal as I need to do some operations before triggerId expires. Once I have my View prepared, I update( slack.methods().viewsUpdate() ) the modal.

• It's working fine locally but on production above mentioned error getting logged sometimes. When I try to reproduce from the same message it doesn't give any error. So I'm not aware of any specific circumstance how it's coming.
• Using a mixture of both, bolt for BlockActionRequest. For modal open and update using Slack API like this:

  static final Slack slack = new Slack();
  .
  .
  .
  // open modal
  ViewsOpenResponse response = slack.methods().viewsOpen(r -> r
                  .token(botToken)
                  .triggerId(triggerId)
                  .view(view));
  .
  .
  .
  // update modal
  ViewsUpdateResponse updateResponse = slack.methods().viewsUpdate(r -> r
                  .token(botToken)
                  .viewId(previousView.getId())
                  .hash(previousView.getHash())
                  .view(view)

  Does this matter using Bolt or Slack API Client?

• As I explained the complete flow above, update takes place after sometime

Please let me know if you need anything else :)

This may not be your case but one possible cause would be a scenario that an end-user closes the modal before your app peforms views.update API call.

[kranti-rh]

@seratch I tried closing the modal and got the same error logged. So, I guess the end user is closing the modal as they think it's taking much time. There is nothing we can do about that as a developer, right?

Closing this issue as it doesn't seem to be an issue that needs any action from the Slack team. Thanks!
