Slack Modal Form Submission Throws Error After Clicking "Submit"

Describe the problem/error/question

The Slack modal form opens successfully using views.open, but when a user clicks the Submit button, an error is thrown. The expected behavior is for the submission data to be captured and processed in n8n, but instead, Slack reports a failure.

What is the error message (if any)?
