    /**
     * 
     * Creates a Lambda function. To create a function, you need a deployment package and an 
     * execution role. The deployment package is a .zip file archive or container image that contains your function
     * code. The execution role grants the function permission to use AWS services, such as Amazon CloudWatch Logs for
     * log streaming and AWS X-Ray for request tracing.
     * 
     * 
     * When you create a function, Lambda provisions an instance of the function and its supporting resources. If your
     * function connects to a VPC, this process can take a minute or so. During this time, you can't invoke or modify
     * the function. The State, StateReason, and StateReasonCode fields in the
     * response from GetFunctionConfiguration indicate when the function is ready to invoke. For more
     * information, see Function
     * States.
     * 
     * 
     * A function has an unpublished version, and can have published versions and aliases. The unpublished version
     * changes when you update your function's code and configuration. A published version is a snapshot of your
     * function code and configuration that can't be changed. An alias is a named resource that maps to a version, and
     * can be changed to map to a different version. Use the Publish parameter to create version
     * 1 of your function from its initial configuration.
     * 
     * 
     * The other parameters let you configure version-specific and function-level settings. You can modify
     * version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both
     * the unpublished and published versions of the function, and include tags (TagResource) and per-function
     * concurrency limits (PutFunctionConcurrency).
     * 
     * 
     * You can use code signing if your deployment package is a .zip file archive. To enable code signing for this
     * function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with
     * UpdateFunctionCode, Lambda checks that the code package has a valid signature from a trusted publisher.
     * The code-signing configuration includes set set of signing profiles, which define the trusted publishers for this
     * function.
     * 
     * 
     * If another account or an AWS service invokes your function, use AddPermission to grant permission by
     * creating a resource-based IAM policy. You can grant permissions at the function level, on a version, or on an
     * alias.
     * 
     * 
     * To invoke your function directly, use Invoke. To invoke your function in response to events in other AWS
     * services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in
     * the other service. For more information, see Invoking Functions.

     * Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or
     * asynchronously. To invoke a function asynchronously, set InvocationType to Event.
     * 
     * 
     * For synchronous invocation,
     * details about the function response, including errors, are included in the response body and headers. For either
     * invocation type, you can find more information in the execution log and trace.
     * 
     * 
     * When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client,
     * event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error,
     * Lambda executes the function up to two more times. For more information, see Retry Behavior.
     * 
     * 
     * For asynchronous invocation,
     * Lambda adds events to a queue before sending them to your function. If your function does not have enough
     * capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event
     * multiple times, even if no error occurs. To retain events that were not processed, configure your function with a
     * dead-letter queue.
     * 
     * 
     * The status code in the API response doesn't reflect function errors. Error codes are reserved for errors that
     * prevent your function from executing, such as permissions errors, limit errors, or issues with your function's

     * For functions with a long timeout, your client might be disconnected during synchronous invocation while it waits

     *         specified as part of Lambda function configuration, because the limit for network interfaces has been
     *         reached.
     *         EfsMountConnectivityException The function couldn't make a network connection to the configured file
     *         system.

     *         system, but the mount operation timed out.
     *         EfsioException An error occured when reading from or writing to a connected file system.
     *         Ec2ThrottledException AWS Lambda was throttled by Amazon EC2 during Lambda function initialization
     *         using the execution role provided for the Lambda function.
     *         Ec2AccessDeniedException Need additional permissions to configure VPC settings.
     *         InvalidSubnetIdException The Subnet ID provided in the Lambda function VPC configuration is invalid.

     *         KmsInvalidStateException Lambda was unable to decrypt the environment variables because the KMS key
     *         used is in an invalid state for Decrypt. Check the function's KMS key settings.

     * {@link #listEventSourceMappings(software.amazon.awssdk.services.lambda.model.ListEventSourceMappingsRequest)}
     * operation. The return type is a custom publisher that can be subscribed to request a stream of response pages.
     * SDK will internally handle making service calls for you.
     * 
     * 
     * When the operation is called, an instance of this class is returned. At this point, no service calls are made yet
     * and so there is no guarantee that the request is valid. If there are errors in your request, you will see the
     * failures only after you start streaming the data. The subscribe method should be called as a request to start
     * streaming data. For more info, see
     * {@link org.reactivestreams.Publisher#subscribe(org.reactivestreams.Subscriber)}. Each call to the subscribe
     * method will result in a new {@link org.reactivestreams.Subscription} i.e., a new contract to stream data from the
     * starting request.
     * 
     *
     * 
     * The following are few ways to use the response class:
     * 
     * 1) Using the subscribe helper method
     * 
     *      * {@code
     * software.amazon.awssdk.services.lambda.paginators.ListEventSourceMappingsPublisher publisher = client.listEventSourceMappingsPaginator(request);
     * CompletableFuture future = publisher.subscribe(res -> { // Do something with the response });
     * future.get();
     * }
     * 
     *
     * 2) Using a custom subscriber
     * 
     *      * {@code
     * software.amazon.awssdk.services.lambda.paginators.ListEventSourceMappingsPublisher publisher = client.listEventSourceMappingsPaginator(request);
