// Use this resource to invoke a lambda function. The lambda function is invoked with the [RequestResponse](https://docs.aws.amazon.com/lambda/latest/dg/API_Invoke.html#API_Invoke_RequestSyntax) invocation type.
//
// > **NOTE:** This resource _only_ invokes the function when the arguments call for a create or update. In other words, after an initial invocation on _apply_, if the arguments do not change, a subsequent _apply_ does not invoke the function again. To dynamically invoke the function, see the `triggers` example below. To always invoke a function on each _apply_, see the `lambda.Invocation` data source.
//
// > **NOTE:** If you get a `KMSAccessDeniedException: Lambda was unable to decrypt the environment variables because KMS access was denied` error when invoking an `lambda.Function` with environment variables, the IAM role associated with the function may have been deleted and recreated _after_ the function was created. You can fix the problem two ways: 1) updating the function's role to another role and then updating it back again to the recreated role, or 2) by using Pulumi to `taint` the function and `apply` your configuration again to recreate the function. (When you create a function, Lambda grants permissions on the KMS key to the function's IAM role. If the IAM role is recreated, the grant is no longer valid. Changing the function's role or recreating the function causes Lambda to update the grant.)
//
// ## Example Usage
// ### Dynamic Invocation Example Using Triggers
//
// ```go
// package main
//
// import (
//
//	"crypto/sha1"
//	"encoding/json"
//	"fmt"
//
//	"github.com/pulumi/pulumi-aws/sdk/v5/go/aws/lambda"
//	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
//
// )
//
//	func sha1Hash(input string) string {
//		hash := sha1.Sum([]byte(input))
//		return hex.EncodeToString(hash[:])
//	}
//
//	func main() {
//		pulumi.Run(func(ctx *pulumi.Context) error {
//			tmpJSON0, err := json.Marshal([]interface{}{
//				aws_lambda_function.Example.Environment,
//			})
//			if err != nil {
//				return err
//			}
//			json0 := string(tmpJSON0)
//			tmpJSON1, err := json.Marshal(map[string]interface{}{
//				"key1": "value1",
//				"key2": "value2",
//			})
//			if err != nil {
//				return err
//			}
//			json1 := string(tmpJSON1)
//			_, err = lambda.NewInvocation(ctx, "example", &lambda.InvocationArgs{
//				FunctionName: pulumi.Any(aws_lambda_function.Lambda_function_test.Function_name),
//				Triggers: pulumi.StringMap{
//					"redeployment": sha1Hash(json0),
//				},
//				Input: pulumi.String(json1),
//			})
//			if err != nil {
//				return err
//			}
//			return nil
//		})
