描述

area:async area:sync discussion enhancement

Is there a way to make it so that the lazy function triggers conditionally based on the ack response?

For example, I want my ack to do parameter validation and potentially reject the request. Right now, my solution is to have the lazy function run the same parameter validation as the ack function, but it seems a bit wasteful. I'd much rather the lazy function not get triggered at all in the scenario where the ack function returns errors to the user.

Reproducible in:
The slack_bolt version

slack-bolt==1.9.1

Python runtime version

Python 3.8.12

OS info
ProductName:    macOS
ProductVersion: 11.5.2
BuildVersion:   20G95
Darwin Kernel Version 20.6.0: Wed Jun 23 00:26:31 PDT 2021; root:xnu-7195.141.2~5/RELEASE_X86_64
Steps to reproduce:

Run something like this:

def validate_the_stuff(ack, view):
    #errors = validate_inputs(view)
    errors = { "environment-select-block": "Nope" }
    if len(errors) > 0:
        ack(response_action="errors", errors=errors)
        return False
    else:
        ack(response_action="clear")

def do_the_thing(view):
    logging.error("You should not get this far")

app.view_submission('environment_select_submit')(
    ack=validate_the_stuff,
    lazy=[do_the_thing]
)
Expected result:

Don't do the thing if validation fails.

Actual result:

Does the thing even if validation fails.
