Summary
Sometimes we get the below warning message in the Confluence application logs. This is related to App link corruption.
2021-02-10 13:25:52,418 WARN [Caesium-1-4] [atlassian.applinks.core.DefaultApplicationLinkService] retrieveApplicationLink Couldn't find type id for application link with id 973662fd-910f-3593-897f-b0464b2fc5fb. Link is corrupted
2021-02-10 13:26:52,418 WARN [Caesium-1-4] [atlassian.applinks.core.DefaultApplicationLinkService] retrieveApplicationLink Couldn't find type id for application link with id 973662fd-910f-3593-897f-b0464b2fc5fb. Link is corrupted Diagnosis
We can check the App link configuration in Confluence Support Zip and Jira App link ServerID.
Also, we can run the CURL command and SQL for getting any App link that is corrupted in the Database and matches the corrupted link SERVERID from the CURL Command and SQL output.
curl -s -X GET -u <username>:<password> -H "Accept: application/json" <Confluence-Base-URL>/rest/applinks/1.0/listApplicationlinks | python -mjson.tool
Execute the following database query and return the result:
select * from bandana where bandanakey like '%applink%';
If you get such output like below where 2 APP Link ID found in the Bandana Table and in that 1 is active and other is the corrupted one and matching with the Warning message.
BANDANAID | BANDANACONTEXT | BANDANAKEY | BANDANAVALUE |
12 | _GLOBAL | applinks.global.application.ids | <list> <string>973662fd-910f-3593-897f-b0464b2fc5fb</string> <string>603c9d5b-36dd-3890-b7a5-f6504b043c69</string> </list> |
Cause
Sometimes, AppLink deletion fails and can cause the AppLink corruption. Some data will be left in the database and that can also cause this AppLink corruption warning messages in the application logs.
Solution
Remove the corrupted records from the Database and update the applinks.global.application.ids with proper/active App link ID.
Stop Confluence.
Execute the below update statement with the the active APP link ServerID.
Always back up your data before performing any modifications to the database. If possible, test any alter, insert, update, or delete SQL commands on a staging server first.
UPDATE BANDANA SET
BANDANAVALUE = '<list>
<string>603c9d5b-36dd-3890-b7a5-f6504b043c69</string>
</list>'
WHERE BANDANAKEY = 'applinks.global.application.ids';
commit;Start Confluence.
This will fix the AppLink corruption warning messages that previously appeared.
