Hello,

In my SP2013 environment Job"ProductVersionJobDefinition"is getting failed continuously.

It throws Event ID:6398 in the event viewer with below details:

The Execute method of job definition Microsoft.SharePoint.Administration.SPProductVersionJobDefinition (ID b8218ef6-e70d-492b-a154-6dc3ce8703bc) threw an exception. More information is included below.

I checked in the ULS Logs and it shows below Error:

I have tried so far below steps to resolve issue but no luck :(

• Restarted the Server
• Get-SPProduct -Local
• Ran PSConfig Wizard
• Cleared the SharePoint timer Cache

Please help me find out the root cause and resolve this issue

Thanks in advance.
