Routinely being met with the same error when uploading CSV to JIRA.

[Jordan Williams]

Hi.

I have a Team-managed project in JIRA that I am the administrator for. I am attempting to make changes to pre-existing JIRA issues via the CSV upload tool in JIRA.

I have followed various tips online and in the tool itself explaining the necessary fields to make this work. Each time I am met with the following error:

ERROR - Unexpected failure occurred. Importer will stop immediately. Data may be in an unstable state: Failed to remove subtasks [SDS-136] parents. A parent of a subtask cannot be removed.

The bizarre part of this is that all I am attempting to change is one custom text field, but for whatever reason, I am met with the above error.

I initially attempted applying my changes to 'Task' level issues, but that resulted in my issues becoming unallocated from their assigned 'Epic'. Believing this to be cause by some bizarre 'Epic-Task' relationship bug, I tried to apply my updates to 'Subtask' level issues, and the error above appeared.

I am at my wits end with this as all online materials show a very simply process to follow, but it never works. Please help.

Below is an example of the data I am trying to upload (but is not succeeding):

Issue key	Summary	Custom field (Target Location(s))
SDS-136	Stream 277_GD	\\folder\folder2\folder3

 I have been mapping these to their corresponding fields in the upload tool.

Issue key > Issue Key

Summary > Summary

Custom field (Target Location(s)) > Target Location(s) [custom field]

Any tips to navigate this issue would be most welcome. I have tried also defining parent and child relationships in my upload with no success (perhaps some direction on how to best achieve this would help).

Kind regards,
J

Hi Jordan : )

There are two problems here, let's go though them one by one:

• The error encountered updating existing subtasks
  It's hard to tell what is exactly the problem but judging by the error message 

  Failed to remove subtasks [SDS-136] parents. A parent of a subtask cannot be removed.

  It seems that there was a mapping to remove the parent field on this subtask. Can you please check the parent of subtask SDS-136 and make sure it has a valid parent issue? 
  
  
• The parent/child mapping
  This is a known limitation to import issues with parent-child(epic-task) relationship to a team-managed project. https://jira.atlassian.com/browse/JRACLOUD-83172
