描述

Describe the issue

It seems that the timeout argument to new cdk.aws_stepfunctions.StateMachine is only applied when the definitionBody is a ChainDefinitionBody. The only reference I can find is here: https://github.com/aws/aws-cdk/blob/ebfaf89e6a9018d19eb29dcb42f2a1ec93e81d57/packages/aws-cdk-lib/aws-stepfunctions/lib/state-machine.ts#L486

This behavior is unclear from the documentation: https://github.com/aws/aws-cdk/blob/ebfaf89e6a9018d19eb29dcb42f2a1ec93e81d57/packages/aws-cdk-lib/aws-stepfunctions/lib/state-machine.ts#L127

For users that provide a .asl.json definitionBody, this can cause unexpected behavior.

研究方向
Examine the StateMachine constructor in packages/aws cdk lib/aws stepfunctions/lib/state machine.ts, specifically around line 486 where timeout is applied only for ChainDefinitionBody. Investigate the behavior for .asl.json definitionBody and check if timeout is missing. Look at existing tests for timeout to ensure compatibility. The fix likely involves extending timeout application to all definition body types.
