jira automation change the field "resolutiondate"

Question

I've created an automation rule in jira datacenter

In edit field these options:

the customfield is working but the resolution date not.

{
"fields": {
"resolutiondate": "{{now}}",
"customfield_31006": "the value I want to set"
}
}

The error obtained is the next one:

Edit issue

The problem I have is that I have imported a large number of cases from Freshdesk. All these historical cases are now in JIRA.
However, the Freshdesk ResolveDate has not populated the resolutiondate in JIRA.
I have created a PowerAutomate API routine that can go and fetch that and populate a custom field in JIRA but there is no way of updating the reolutiondate field in JIRA with the historical resolution date from either the original Freshdesk case or the custom filed in jira. This is not useful when reports rely on that field to be correctly set.

Exporting & Importing cases seems to be the only option but I do not wish to risk that on a live system.

Surely dear Atlassian developers, you can do something to help in such a situation?

Looking for something else and found a few questions like this. I would think rather than using automation to set the resolution field, you'd want to use automation to transition the issue, then the transition will set the resolution and the date.

Is this a known bug? We are running into the same problem. Using automation we are setting the resolution to duplicate, but the resolutiondate is empty? We are on DataCenter.
