Common issues

Bundle the latest AWS SDK with your Lambda functions

If you are calling Connect AI agents APIs directly from Lambda functions, you must package and bundle the latest version of the AWS SDK along with your function code. The Lambda runtime environment may include an older version of the SDK that does not support the latest Connect AI agents API models and features.

Symptoms: You may experience parameter validation exceptions or request input parameters being silently ignored when using an outdated SDK version.

To avoid API model drift, include the latest AWS SDK as a dependency in your deployment package or as a Lambda layer rather than relying on the SDK provided by the Lambda runtime. The steps to bundle the SDK vary by language. For example, for Node.js, see Creating a deployment package with dependencies. For other languages, refer to the corresponding Lambda deployment packaging documentation. For sharing the SDK across multiple functions, see Lambda layers.
