When import a CSV file to create JIRA, there is error message about parent ID selection

[tianchi]

See above error, but I did put in the error message in the CSV, no idea why the error shows up.

Hi @tianchi 

Kindly see these instruction to import your csv https://support.atlassian.com/jira-cloud-administration/docs/import-data-from-a-csv-file/

Especially:

Creating sub-tasks

You can create sub-tasks of issues by:

• Adding two columns to your CSV file with the headings "Issue Id" and "Parent Id"

• Ensuring each regular (non sub-task) issue is given a unique (sequential) number in the "Issue Id" column. Do not include any value in the "Parent Id" fields for regular issues.

• Referencing the unique "Issue Id" number of the regular issue in the "Parent Id" column. Do not include any value in the "Issue Id" fields for sub-tasks.
