Set a field to empty for all the results in lookup issues

[Manoj Lingaiah]

I am trying to create an automation rule (Manual Trigger) that should find all the issues that are in cancelled status and set a "Fix versions" field to empty

For the below list of issues,
JQL used
project = XX AND issuetype in (Story,Sub-task) AND status = Cancelled AND fixVersion is not EMPTY 

I need to set FixVersion to empty. I dont know how to do it for lookupIssues
{
"fields": {
"Fix Versions": {{lookupIssues.Fix Versions.value|null}}
}
}
