The problem is when it comes to exporting. The user won't be able to export any files.


Possible Cause

Not using a valid locale. On the logs you'll find an error like this:

Log Error
2020-01-15 15:16:17,732 (...) [c.x.jiraxporter.workflow.XporterPostFunctionAction] Error performing post function class
com.aspose.pdf.internal.ms.System.lh: Culture Name: es-ES-ES is not a supported culture

Solution

Use this link to see Implementation Examples and validate in the Jira instance if the locale is still as shown in the link. If yes, then it should be switched to a valid locale (en-US), and Jira Host needs to be restarted.

Also, this can happen when the setenv.sh file is configured within the parameters JVM_SUPPORT_RECOMMENDED_ARGS various attributes, removing those attributes that referenced the language and localization will solve the problem:

-Duser.language=es -Duser.country=ES -Duser.variant=ES -Duser.timezone=Europe/Madrid

Leaving these parameters applied only from the JIRA application itself configured to the locale language it was being used, will fix the problem.
