[BUG] DDBClient does not validate request fields #154
Description
What is the bug?
Fields such as the id and index are not validated in the DynamoDB client.
This impacts parsing of the JSON text generated to serialize a DDB response into an OpenSearch response object.
How can one reproduce the bug?
Attempt to use a document ID or index containing characters which break JSON parsing, such as a single quote. Get a 500 error when the parsing fails.
What is the expected behavior?
User receives a 400-series error describing what is invalid.
Do you have any additional context?
Searching the OpenSearch codebase for an ActionRequestValidationException shows some validations.
Here the DocWriteRequest has a 512-character validation.
