500 error
Problem
Error: Confluence server error: put: 500
or similar error
or any error with 500 code
Solution
Any error with the code 500 is an internal Confluence error which means the Confluence server has received a valid request but has an internal issue. These are by definition bugs or issues internal to the Confluence server. We will try to help understand the cause of the issue and a work around where possible, but please understand this an Atlassian issue and ultimately might be best for us to open a ticket @ support.atlassian.com
This is an Atlassian Confluence core error
All 500 errors are by definition issues with Confluence and not our app.  If it were otherwise we'd receive a different error.
An example of a more detailed error.
