How to manage errors?

[lucafx]

Hello everybody,

I'm using this FW to build a slack bot, but i don't have any idea on how to manage errors and restrictions.

There are some actions in the bot dedicated to only a part of the customers (but visible to everybody) and i'd like to do do some kind of error message describing why that action wasn't possible etc.

The only way idea that come in my mind to reach this goal is to use a modal for each different exception, but i should write a lot of different cases to manage every scenario.

Is there anything that i didn't find that can help me?

Thank you very much!

Luca

Hi @lucafx - Yes, a pretty common pattern we see is people updating a modal view with an error message if a user takes an action thats invalid for some business reason.

You might have a modal (view) composed of some input fields or buttons. Slack will send interaction payloads (assuming you have that configured on your app) based on the type of action, here's some basic documentation on view interaction payloads.

In response to a block_action or a view_submission or some other form of interaction payload, or you may supply an error as part of a response_action when your app acknowledges (ack()) the Slack request or if you'd like more control over how the error appears, you may also consider updating the view itself to show some blocks with an error message.
