wish helps you The ValueError here means that the key 'mvid' was never set in your dict. This is different than if item['mvid'] was set to None or an empty string for example.
You can do:
code :
if 'mvid' not in item:
    # Do something
try:
   print item['mvid']
except ValueError:
   # Handle error

it should still fix some issue Types of empty (from PHP Manual). The following are considered empty for any variable:
"" (an empty string) 0 (0 as an integer) "0" (0 as a string) NULL FALSE array() (an empty array) var $var; (a variable declared, but without a value in a class)
code :
$arr = array(
          'ele1' => 'test',
          'ele2' => false           
       );

wish of those help The getItem response doesn't include Items, it includes Item (see the documentation). It will return one item, if there is an item with the given key, or no item.
You can detect this as follows:
code :
const AWS = require('aws-sdk');

const ddb = new AWS.DynamoDB({ region: 'us-east-1' });

const params = {
  Key: {
    'groupName': {
      S: groupname,
    },
  },
  TableName: 'group',
};

ddb.getItem(params, (err, data) => {
  if (err) {
    console.log(err, err.stack);
  } else if (data.Item) {
    console.log(JSON.stringify(data));
  } else {
    console.log('Success, but no item');
  }
});

I think the issue was by ths following , No, you can't tell how many element in an array are empty without visiting them. You can use any and all, both of which iterate internally though:
code :
val withEmpty = arrayOf("", "a")
val allEmpty = arrayOf("", "")
println(withEmpty.any { it.isEmpty() }) //true
println(allEmpty.all { it.isEmpty() }) //true
