Review comment (suggestion):
The `mergedAt` field is missing from the JSON query but is required on line 882 where `$prDetailData.mergedAt` is accessed. Add `mergedAt` to the list of fields: `--json number,title,url,baseRefName,closedAt,mergeCommit,labels,files,state,body,comments,reviews,closingIssuesReferences,commits,mergedAt`
```suggestion
        $prDetails = gh pr view $pr.number --repo $Config.SourceRepo --json number,title,url,baseRefName,closedAt,mergeCommit,labels,files,state,body,comments,reviews,closingIssuesReferences,commits,mergedAt
