Space import error: nameMapping should not be null

Question

Problem: I can't import a space from Confluence Cloud to Confluence Cloud.

Steps to reproduce:
1. I exported a space from the source Confluence Cloud site in CSV format using the admin user.

2. I downloaded the resulting zip file to my local computer.

3. I log in to the destination Confluence Cloud as an admin user.

4. I imported the space in Settings > Data management > Import spaces.

5. I selected the downloaded zip file.

6. After 5 minutes, I received an error saying that "nameMapping should not be null".

How can I fix this error or get more information about it?

Thank you so much in advance.

Hi @Benjamin ,

Thank you so much for your quick response.

We are currently using Confluence Cloud Free so we can't open a ticket directly to Atlassian support. We hope that someone in the community would have faced a similar problem and could guide us to a solution or workaround.

Any ideas on how to solve this error?

Regards.

Welcome @Raúl Castilla Bravo ,

Looks like you are following are the appropriate steps in the documentation:

https://support.atlassian.com/confluence-cloud/docs/import-a-confluence-cloud-space/

In order to get more information about what might be causing the error, would submit a ticket to Atlassian to have support investigate as the team will have visibility into those logs.
