Login error when running pre-upgrade tasks

[#1]

Hello,

I'm trying to run the 'detectUsageOfUnavailableAPI' operation of PreUpgradeTasks Mbean on AEM 6.3 but get the following error when doing so:

com.adobe.aem.upgrade.prechecks.mbean.impl.PreUpgradeTasksMBeanImpl Cannot login into repository:

org.apache.sling.api.resource.LoginException: Cannot derive user name for bundle com.day.cq.pre-upgrade-tasks [146] and sub service null

Does anyone know why this is so? Any user that needs to be configured before running these tasks?

Thanks.

Usually, this error is observed when the service user mapping is missing to the pre-upgrade bundle. Can you add the mapping as per below and check if you still get the same issue?

• Go to the Web Console at http://serverhost:serveraddress/system/console/configMgr
• Search for Apache Sling Service User Mapper Service Amendment and click on +
• Add the mapping as per below:

Thanks for the reply. But I'm still getting the same error even after this change.

Can you go to <host>:<port>/useradmin and check if "preupgrade-service" is an actual service user in AEM?
