Answer

If your view is similar to below, then ensure that you enable a DynamoDB stream on at least one table.

If you don't get that far, ensure the role you are creating the trigger with has the necessary DynamoDB roles, such as ListTables/DescribeTable/ListStreams/DescribeStream

Answer

Does your Lambda have the proper policy in place?
Your lambda needs to have access to the following operations on the dynamodb db stream arn

```json
 ["dynamodb:GetRecords",
      "dynamodb:GetShardIterator",
      "dynamodb:DescribeStream",
      "dynamodb:ListStreams"]
```
