mc: <ERROR> Unable to initialize service restart UI: could not open a new TTY: open /dev/tty: no such device or address.

Expected behavior

No error, service restarts.

Actual behavior

Error gets printed, the restart doesn't fail

Steps to reproduce the behavior

1. docker-compose.yml:

services:
  minio:
    image: minio/minio:latest
    restart: always
    ports:
      - '9000:9000'
      - '9001:9001'
    volumes:
      - ./.volumes/minio-data:/data
    environment:
      MINIO_ROOT_USER: minio
      MINIO_ROOT_PASSWORD: minio123
    command: server /data --console-address ":9001"

  minio-init:
    image: minio/mc:latest
    depends_on:
      - minio
    volumes:
      - ./commands/init-minio.sh:/usr/local/bin/init_minio.sh
    entrypoint: sh -c
    command: /usr/local/bin/init_minio.sh

2. commands/init-minio.sh:

#!/bin/bash

until mc alias set local http://minio:9000 minio minio123; do sleep 1; done;
mc admin config set local notify_webhook:1 endpoint=http://host.docker.internal:8000/report auth_token=ignore
mc admin service restart local
echo "exit: $?"

3. docker compose up, which prints:

Added `local` successfully.
Successfully applied new settings.
Please restart your server 'mc admin service restart local'.

exit: 1

For what it's worth, adding tty: true to minio-init "fixes" the problem, but it becomes incredibly slow
