appstoreagent service exits with abnormal code 1 every ten seconds

I have the following message in my log apparently repeating every ten seconds indefinitely

Oct 20 17:04:41 BradleyRossMacBook com.apple.xpc.launchd[1] (com.apple.appstoreagent[34289]): Service exited with abnormal code: 1

Oct 20 17:04:41 BradleyRossMacBook com.apple.xpc.launchd[1] (com.apple.appstoreagent): Service only ran for 5 seconds. Pushing respawn out by 5 seconds.

There is a file com.apple.appstoreagent.plist in the /System/Library/LaunchAgents folder dated 14-September-2019. I'm not sure if the problem predated the upgrade to Catalina, since I only noticed it after the installation. I'm not sure how serious this is or what I'm supposed to do about it.
