💡 Hint

Common Mistakes

Using 'yellow' or 'red' which do not indicate full cluster health.

To wait until the cluster status is green, use wait_for_status=green.

💡 Hint

Common Mistakes

Using '60s' timeout with 'yellow' status which is less healthy.

Use timeout=30s to set a 30-second timeout and wait_for_status=green to wait for green status.

Using 'green' status when the task asks for yellow.

Setting timeout too low or missing it.

Specify the index as my_index, wait for yellow status, and set timeout to 50 seconds.
