Bug report: panic: interface conversion: interface {} is string, not int

[benjaminwood]

My docker-compose version is 2.24.7-1:

> docker-compose --version
Docker Compose version 2.24.7-1

The following service causes a panic. Specifically soft: "262144" and hard: "262144". If I remove the quotes to change the values to numbers, it works fine. Still, I figure it shouldn't cause a panic if the type isn't right.

services:
  clickhouse:
    image: clickhouse/clickhouse-server:23.9
    container_name: clickhouse
    environment:
      - "CLICKHOUSE_DB=...."
      - "CLICKHOUSE_PASSWORD=...."
    volumes:
      - clickhouse_data:/var/lib/clickhouse
      - clickhouse_logs:/var/lib/clickhouse-server
    ports:
      - "8123:8123"
      - "9000:9000"
    ulimits:
      nofile:
        soft: "262144"
        hard: "262144"
