[Solved] DataX Error

[icexxxxxx]

[Solved] There are several hidden files start with ._ and list does not show them. Solving by deleting them.

Solution or help wanted.

Following the instruction Quick Start with docker compose, I have met such problems:

1. Auto generated postgres DDL was wrong, id is not serial. Solved by switching to MySQL in docker-compose.yml.
2. There is no datax folder in /opt/soft in official image based container. Solved by COPY datax /opt/soft with manually downloaded DataX release. HOWEVER, the error I copied below keeps blocking in the way.

PLEASE help me on this. I am new to developing & deploying ETL related platforms. 💥😥🤷‍♂️

	经DataX智能分析,该任务最可能的错误原因是:

I am using the json tpl like this:

{
  "job": {
    "content": [
      {
        "reader": {
          "name": "mysqlreader",
          "parameter": {
            "username": "",
            "password": "",
            "column": [],
            "connection": []
          }
        },
        "writer": {
          "name": "mysqlwriter",
          "parameter": {
            "writeMode": "insert",
            "username": "",
            "password": "",
            "column": [],
            "connection": []
          }
        }
      }
    ]
  }
}
