How to resolve "Error importing data: java.lang.NumberFormatException: For input string: "nuse"" when importing JIRA cloud data to JIRA server?

[FullName]

We are looking to migrate from cloud to server, and we are currently performing a trial import\export. We are getting the following error when importing to the local server instance of JIRA.

For info, I am taking the ZIP file from JIRA cloud WebDav, dropping it off in \application data\JIRA\import on the server, then attempting to import via System -> Restore system and inputting the zip file name.

Error importing data: java.lang.NumberFormatException: For input string: "nuse"

We are using JIRA Server v7.2.2 and the export was taken from JIRA cloud v1000.383.2

What does this error mean? How can we resolve it? Is there something obvious that I'm doing wrong?

The problem occures because \n (or just \) isn't escaped, at least in Active Objects export.

You should open a case with Atlassian Support - I'll be happy to help fill out more details if you put me Cc: on the case.
