Verify Job Configuration Parameter error

[huyuanfeng2018]

Describe the bug
An error occurred in the code in the validation check of the writer parameter after submitting the task
code

  Map<String, Object> writerParameter = reader.getParameter();
        Preconditions.checkNotNull(
                writerParameter,
                "[parameter] under [writer] in the task script is empty, please check the configuration of the task script.");

This should be to verify the writer parameters but inherit the reader
