I want to prevent users from editing a field (Customer desired Go Live) on standard issues under an epic. To do that, I'm using the log audit to capture the change and then setting the field back to the prior value.

I am consistently getting this date format mismatch error. I've tried a number of variations to the fieldChange including
- {{fieldChange.fromString.toDate.format("yyyy-MM-dd")}}
- {{fieldChange.fromString.toDate("yyyy-MM-dd")}}
- {{fieldChange.from.toDate("yyyy-MM-dd")}}
but they are all failing - sometimes because nothing is written to the audit and, in the case of {{fieldChange.fromString.toDate.format("yyyy-MM-dd")}} the date isn't getting transformed.

I've tried reviewing a number of posts and the Atlassian documentation without success. Thanks for your help.
