Environment

  • VMware Aria Suite LifeCycle 8.18.x

Cause

  • The issue occurs due to a known bug in the vmlcm-service-8.18.0-SNAPSHOT.jar file.
  • The existing JAR file cannot fetch the content library due to a defect property. 
  • Replacing the JAR file and restarting the service resolves the issue.

Resolution

  • Take a snapshot of Aria LCM. 
  • Download the updated vmlcm-service-8.18.0-SNAPSHOT.jar file (Open a SR with GSS to get the file) 
  • SSH into vRSLCM as root.
  • Backup the existing JAR file from /var/lib/vrlcm.
  • Replace it with the new downloaded JAR file.
  • Restart the vRSLCM service using:
    systemctl restart vrlcm-server
  • Verify the service status:
    systemctl status vrlcm-server
  • Once the UI is accessible, retry the vCenter data collection.

  Issue with Aria Automation Custom form Multi Value Picker and Data Grid https://knowledge.broadcom.com/external/article?articleNumber=345960 Products VMware Aria Suite Issue/Introduction Symptoms: Getting  error " Expected Type String but was Object ", w hen trying to use Complex Types in MultiValue Picker on the Aria for Automation Custom Form. Environment VMware vRealize Automation 8.x Cause This issue has been identified where the problem appears when a single column Multi Value Picker or Data Grid is used. Resolution This is a known issue. There is a workaround.  Workaround: As a workaround, try adding one empty column in the Multivalue picker without filling the options. So we can add one more column without filling the value which will be hidden(there is a button in the designer page that will hide the column). This way the end user will receive the same view.
