JIRA -> Slack webhook integration not working post update

After updating to JIRA version 7.3.3, our JIRA -> Slack integration via webhooks has stopped working. I've used requestbin to identify any potential issues with the request. 

It appears the the request payload is being truncated to 7495 characters, meaning that the json being sent to Slack is invalid. Is this an known issue?

Hi Sean,

So we are on the same JIRA version.  A JIRA API webhook does work to our Slack.  However I cannot get a plain incoming Slack webhook to work from JIRA as a post workflow trigger.  Simply get 404 or 500 error messages in JIRA log.

Wondering if you were able to get any resolution on your issue or any advice?  We are thinking of potentially using the Slack to JIRA marketplace add-on.

Many thanks,
