ValidateStateMachineDefinition

Source: src/AWS/StepFunctions/ValidateStateMachineDefinition.ts

Runtime binding for states:ValidateStateMachineDefinition — AWS’s static ASL validator (the Tier-4 check op for the Step Functions DSL).

Service-scoped (no resource argument): validates any definition string without creating or updating a state machine. StateMachine’s reconcile runs this same check as a pre-flight; bind it in a function runtime to validate definitions on demand (e.g. compiled Sfn programs before a deployment pipeline applies them).

Validating Definitions

const validate = yield* StepFunctions.ValidateStateMachineDefinition();

const report = yield* validate({
  definition: JSON.stringify(definition),
  type: "EXPRESS",
  severity: "ERROR",
});
// report.result === "OK" | "FAIL"; report.diagnostics lists findings
