I'm sure I've updated tasks in JIRA via CSV before and followed the instructions for doing this as listed here
https://confluence.atlassian.com/adminjiracloud/importing-data-from-csv-776636762.html
If I leave the summary field empty then JIRA says
- Issue can't be created due to the error/s [ You must specify a summary of the issue. ]
However if I populate the summary field with the original titles in then creates new tasks instead.
Has something changed with the plugin or is there a setting on my server I need to change?
(Tested on 7.4.4. and 7.6.4)
Edit:
Plugin jira-importers-plugin 7.1.30 & 8.0.4
Further to this the log file has the following
Caused by: com.atlassian.jira.plugins.importer.imports.csv.ImportException: Blank summary detected. Such issue cannot be imported
