I have created story and Sub-task in CSV file and i tried to upload to Jira cloud but getting the "Fatal error during import: Parent Issue cannot be null". But I have entered the value in issue id and parent field.
Same file i used for Jira server and it worked. Can you please help me to figure out what i am doing wrong here. My CSV file looks like below
| Summary | Issue id | Parent id | Issue Type |
| main story | 1 | | Story |
| Sub task 1 | 2 | 1 | Sub-task |
| Sub task 2 | 3 | 1 | Sub-task |
