Explainer

When a user enters something your Slack app can't accept, the app should tell them what went wrong and let them fix it without starting over. In modals, Slack has a built-in way to do this: the app checks the submitted values and replies with error messages that appear next to the fields that need fixing. Clear, brief wording and good input design, such as labels, hints and prefilled values, help users get it right the first time.
Core information
  • Modal input is checked when the user clicks submit. The app receives a view_submission payload, and the entered values are in view.state.values, organized by block_id and then action_id. In Bolt, you listen for this payload with the view() method and the view's callback_id.
More details and nuances
  • The errors object points at a field only by its block_id, and the app is responsible for setting and tracking block_ids when it composes the view. If you leave block_id out, Slack generates one. Set a unique block_id for each block and a unique action_id for each element so your code can match submitted values and errors to the right fields.
