AWS CLI - Looping through DMS Migration task ARNs to wait

[eternaltyro]

In Github Actions, I tried looping through a list of DMS Migration Tasks (ref by ARN) to check their status using aws dms wait. But I always get Waiter encountered a terminal failure state error.

Waiter ReplicationTaskStopped failed: Waiter encountered a terminal failure state: For expression "ReplicationTasks[].Status" we matched expected path: "starting" at least once
Error: Process completed with exit code 255.

The run step on Github Actions looks like this:

      - name: Trigger DMS Replication Tasks
        run: |
          # Define the list of DMS task ARNs
          TASK_ARNS=(
            "arn:aws:dms:eu-west-2:<AC_ID>:task:<ARN_1>"
            "arn:aws:dms:eu-west-2:<AC_ID>:task:<ARN_2>"
            "arn:aws:dms:eu-west-2:<AC_ID>:task:<ARN_3>"
            "arn:aws:dms:eu-west-2:<AC_ID>:task:<ARN_4>"
          )

          # SUCCEEDS
          for ARN in "${TASK_ARNS[@]}"; do
            echo "Starting DMS Task: $ARN"
            aws dms start-replication-task \
              --replication-task-arn "$ARN" \
              --start-replication-task-type reload-target
          done

          # FAILS
          for ARN in "${TASK_ARNS[@]}"; do
            echo "Checking DMS Migration Task Status: $ARN"
            aws dms wait replication-task-stopped \
              --filters Name=replication-task-arn,Values="$ARN"
          done
