AttributeError: 'NoneType' object has no attribute 'send' when using modal to collect data #461
Description
Hello,
I'm using slack modal to collect some data from user, the modal openned for user is like
The number of comment-department pairs showed in the modal depends on some internal logic.
The modal can be submitted successfully when there are 3 such comment-department pairs, but when there are more than 3 pairs submitted, the following error occurs:

I have no idea why I got this error, and this error only occurs when there are more than 3 comment-department pairs are submitted. Can anyone help me? Thanks a lot.
