When importing comments to issues in Next-Gen projects an error is thrown using the External System Import.
- Create a CSV file containing Summary,Issue key,Issue id,Comment,Issue Type, Parent
- Try to import the CSV file.
The fields are going to be updated and the comment will be imported.
The following error is thrown:
What happens is that the importer will look for a Parent Association for the imported issue and if it does not exists it fails. To work around the behavior create a new Epic and add all the issues into it and then perform the import mapping the Parent -> Parent ID with an empty value.
