...原因
The page has the Popular Label macro in use, but one of the labels has a null value in the label name.
回避策
Confirm this is the problem:
select * from LABEL where NAME is null;
If you want to find details about the content that is using the label:
select CONTENTID from CONTENT_LABEL where LABELID = '<labelid-from-above>'; select * from CONTENT where CONTENTID = '<contentid-from-above>';If there are any results, use the following to update the data where
<some-name>is the name of the label:update LABEL set NAME = '<some-name>' where LABELID = <labelid-from-above>;
- Restart Confluence and go to the page that was causing the issue
