Rest API Null Reference Exception on Node Server

Open tanisman opened this issue 9 months ago • 3 comments

Hi,

I set up the Agile Config using following docker compose:

version: '3.1'

services:
  db:
    image: mariadb
    restart: always
    environment:
      - MARIADB_ROOT_PASSWORD=${DB_PASS}
    volumes:
      - /opt/data:/var/lib/mysql:Z
      - ./setup.sql:/docker-entrypoint-initdb.d/setup.sql
  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080
    depends_on:
      - db
  agile_config_admin:
    image: "kklldog/agile_config:latest"
    restart: always
    ports:
      - 80:5000
    volumes:
      - /etc/localtime:/etc/localtime
    environment:
      - TZ=Europe/Istanbul
      - adminConsole=true
      - db:provider=mysql
      - db:conn= database=${DB_NAME};data source=db;User Id=root;password=${DB_PASS}
    depends_on:
      - db
  agile_config_node1:
    image: "kklldog/agile_config:latest"
    restart: always
    ports:
       - "15001:5000"
    volumes:
      - /etc/localtime:/etc/localtime
    environment:
      - TZ=Europe/Istanbul
      - cluster=true
      - db:provider=mysql
      - db:conn= database=${DB_NAME};data source=db;User Id=root;password=${DB_PASS}
    depends_on:
      - agile_config_admin

I create one App (id: 123) and added a config to that App (key: key1)

when I use GET rest api on the Node Server with the console, everything works as expected:

GET http://localhost/api/Config?appId=123

[
	{
		"id": "0f599ebf3ffb4cfb8157af44aec10b6c",
		"appId": "123",
		"group": "group1",
		"key": "key1",
		"value": "value",
		"status": 1,
		"onlineStatus": 1,
		"editStatus": 10,
		"description": null
	}
]

but when I do same request on the other Node Server:

GET http://localhost:15001/api/Config?appId=123

I get 500 Internal Server Error, below is AgileConfig's produces error output:

It seems Node Server's environment list is null. Any help is highly appreciated.

Thank you.

by the way, other requests such as /api/App/{appId} works as expected on both nodes.

Hi @tanisman Thanks for using agileconfig. It had a bug when a node is not adminconsole it can not init enviornment correctly. I just fix it now. You can update the image to latest or tag: v-1.9.12.

Thanks for your hard work on AgileConfig!
