按https://www.npmjs.com/package/dynamodbexportcsv使用DynamoDbExportCsv时，出现错误：

array (
  2135 => 
  array (
    'id' => 2135,'first_name' => 'John','last_name' => 'Doe',),3245 => 
  array (
    'id' => 3245,'first_name' => 'Sally','last_name' => 'Smith',5342 => 
  array (
    'id' => 5342,'first_name' => 'Jane','last_name' => 'Jones',5623 => 
  array (
    'id' => 5623,'first_name' => 'Peter',)

我的代码如下，但是访问键，表名等已放入代码中。

"stack": [
        "Error: spawn /var/task/node_modules/dynamodbexportcsv/bin/DynamoDbExportCsv EaccES","    at Process.ChildProcess._handle.onexit (internal/child_process.js:240:19)","    at onErrorNT (internal/child_process.js:415:16)","    at process._tickCallback (internal/process/next_tick.js:63:19)"
