# dataset_in_use

A queued or running run uses this dataset, so it cannot be deleted yet.

## What happened

A dataset that a live run request names cannot be removed from under it. The delete is refused with 409, and `request_ids` lists the runs that block it.

## What to do

Wait for those runs to finish, or stop them, then delete the dataset.

  "request_ids": [
    "8f1c2d3e-4b5a-4c6d-9e7f-0a1b2c3d4e5f"
