Harvester task execution returns 500 internal server error

[scook12]

Issue

When attempting to execute a task, the server returns 500 internal server error.

Error Message: In the UI: Error executing task: natres-harvest-server In the dev console: Unable to load rest/harvester/tasks/e748f210-5af0-48f0-8393-5f648819a9df/execute? status: 500

Task - this is accessible at /rest/harvester/tasks/e748f210-5af0-48f0-8393-5f648819a9df:

Expected

The task executes and harvests content or fails gracefully with feedback to the user on whatever caused the failure.

Environment

Provided for context only, the deployment is working fine otherwise for both the geoportal and harvester. I can login, add brokers, add tasks, etc just not execute them.

Only thing in the logs that looked potentially relevant was this warning:

WARNING [http-nio-8080-exec-3] org.springframework.web.servlet.handler.AbstractHandlerExceptionResolver.logException
