bug: StepFunctions: SecondsPath in Wait state throws error

Is there an existing issue for this?

Current Behavior

Using a SecondsPath with a Wait state in a step function definition makes the execution fail with the following error in the logs even though a valid input is provided:

The same step function definition and input work in AWS.

Expected Behavior

The Wait state should take the value from the location specified in SecondsPath and wait for that duration as described in the AWS docs

SecondsPath
A time, in seconds, to wait before beginning the state specified in the Next field, specified using a path from the state's input data.

You must specify an integer value for this field.

How are you starting LocalStack?

With a docker-compose file

Steps To Reproduce

How are you starting localstack (e.g., bin/localstack command, arguments, or docker-compose.yml)

docker-compose up

Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

Create a state machine using either awslocal or the localstack resource browser with the following ASL definition:

{
  "Comment": "Dynamic wait seconds path",
  "StartAt": "Wait",
  "States": {
    "Wait": {
      "Type": "Wait",
      "End": true,
      "SecondsPath": "$.input.waitSeconds"
    }
  }
}

Start an execution of the state machine using either awslocal or the localstack resource browser with the following input:

{
  "input": {
    "waitSeconds": 60
  }
}

The execution fails immediately in LocalStack whereas in AWS the execution proceeds and waits for 60 seconds as expected before completing.

Environment

- OS: macOS 14.1.1
- LocalStack: 3.2.0
