Issue Summary

Creating work item/issue from Slack gives no warning about field validators in Jira Workflow, fails to create issue. If there is a field value required validator on a work type workflow, the Slack pop up will not warn about it, and clicking "Submit" will give no warnings or errors. In Jira, though, the work item will not create, and there's no mention of this anywhere.

Steps to Reproduce

1. add a "Field value required" validator to a "create" transition in a workflow
2. In Slack, create an issue using either the "/Jira create" command or the message actions menu
3. Create an issue, leaving the required field blank, in the project and with the issue type you set in step 1

Expected Results

Some sort of warning or notification if the work item fails to create that can help the user troubleshoot why the work item failed to create

Actual Results

No message, no warning, no error. Work Item fails to create, but there's no indication that this happened

Workaround

Put a default value in the field so that something will be set there
