## Locating Error Logs

* **Note**\
  Task Runner stores its logs in a different location by default, which may be unavailable when the pipeline finishes and the instance that runs Task Runner terminates. For more information, see [Verifying Task Runner Logging](https://github.com/kevinslin/aws-reference-notes/blob/main/services/aws_data_pipeline/dp-how-task-runner-user-managed.md#dp-verify-task-runner).

## Resolving Common Problems

* **Note**\
  If you provide a runsOn value and workerGroup exists, workerGroup is ignored.
* **Note**\
  In this error message, PollForTask may be replaced with names of other AWS Data Pipeline permissions.
