@Sudershan - Glad you got it figured out. Make sure to mark your answer as a solution so others will be more easily find it if they have a similar issue.
Hi @Sudershan which Jira connector are you using? Do the fields you need exist in other reports?
JIRA Rest API.
The following is used to pull the data.
Report: Issue Query
JQL Query: created >= startOfWeek()
DATA Option: Standard Ticket report
Filter Type: Include ( Assignee, Summary, Reporter)
Under data preview,
I see only Issue_key and issue_id and _Batch_last_run
Got the right query and the issue is resolved. Looks like FilterType is case sensitive. Used all lower case letters in include filtertype and it resolved the issue.
