(aws-stepfunctions-tasks): StepFunctionsStartExecution accepts invalid input type

See original GitHub issue

StepFunctionsStartExecution supports an input argument of type TaskInput. If I pass in a value which is not of type TaskInput, CDK successfully built and deployed the Step Functions task, but ignored the input argument. In other words, a CloudFormation template was generated and deployed, but the task input was not included in the template.

Reproduction Steps

new StepFunctionsStartExecution(this, 'ExampleStateMachineStartExecution', {
  input: TaskInput.fromDataAt('$.exampleJsonPath').value,
  stateMachine: 'example-state-machine',
});

What did you expect to happen?

CDK raises an error at build time because TaskInput.fromDataAt('$.exampleJsonPath').value is not of type TaskInput.

What actually happened?

CDK successfully built and deployed the stack. input was not included in the generated CloudFormation template.

Environment

CDK Version : 1.75.0
Language (Version): TypeScript (3.7.5)

It appears the same problem arises in LambdaInvoke, which uses TaskInput for its payload property.
