I have an instance where I want to open(edit) an existing survey record but do not want to make any changes. Effectively, I just want to re-trigger a webhook. When I do this with the webform at version 3.15, it throws an error: "Failed to submit. - 500 unable to complete operation".

I checked the log files an the only error that is thrown is, "An error occured".

If I publish the same survey with version 3.11 I am able to resubmit a survey without making any edits.
I am also finding that webhooks sometimes are triggered and sometimes are not. I search of the forums reveals that I am not the only one with this issue.
Any thoughts why the most current version won't submit an unedited webform?
