Number of attributes in key schema must match the number of attributes defined in attribute definitions

Question

I’m trying to create a simple table using DynamoDB JavaScript shell and I’m getting this exception:

{
  "message&quo

I also had this problem and I'll post here what went wrong for me in case it helps someone else.

In my CreateTableRequest, I had an empty array for the GlobalSecondaryIndexes.

CreateTableRequest createTableRequest = new CreateTableRequest
{
  TableName = TableName,
  ProvisionedThroughput = new ProvisionedThroughput { ReadCapacityUnits = 2, WriteCapacityUnits = 2 },
  KeySchema = new List
  {
     new KeySchemaElement
     {
        AttributeName = "Field1",
        KeyType = KeyType.HASH
     },
     new KeySchemaElement
     {
        AttributeName = "Field2",
        KeyType = KeyType.RANGE
     }
  },
  AttributeDefinitions = new List()
  {
     new AttributeDefinition
     {
         AttributeName = "Field1", 
         AttributeType = ScalarAttributeType.S
     },
     new AttributeDefinition
     {
        AttributeName = "Field2",
        AttributeType = ScalarAttributeType.S
     }
  },
  //GlobalSecondaryIndexes = new List
  //{                            
  //}
};

Commenting out these lines in the table creation solved my problem. So I guess the list has to be null, not empty.
