I use a translation plug-in (Translation for Confluence Cloud: https://marketplace.atlassian.com/apps/1221754/translator-for-confluence?hosting=cloud&tab=overview). In the plugin's settings, translations can be created by users in the confluence-users group, which is everyone. Any of the logged in users can create translations without problems, however I have only one person who has an error in page source when trying to create a translated page. She is, of course, in this group.
The content of the error:
InternalServerError: Failed to copy source page.
at /home/veniture/translation/controllers/apiController.js:363:21
at runMicrotasks (<anonymous>)
at processTicksAndRejections (internal/process/task_queues.js:95:5)
How to solve this problem?
