Walkthrough 4 - Invoke and results

This page covers the fourth stage in the IdLE lifecycle:

Workflow → Request → Plan → Invoke → Providers/Auth

When you invoke a plan, IdLE executes the planned steps in order and emits structured events.

Goal​

Execute the plan and inspect result data (status, step outcomes, events).

You will have​

  • An invocation result object
  • A basic understanding of where to look for success/failure and messages

1) Invoke the plan​

If you supplied providers during plan build, invocation is simple:

$result = Invoke-IdlePlan -Plan $plan

2) Inspect status and step outcomes​

$result.Status

$result.Steps | Select-Object Name, Status, StartedUtc, FinishedUtc

3) Inspect events​

IdLE produces structured events that you can log, forward, or store.

$result.Events | Select-Object Type, StepName, Message

4) If something fails​

Typical first-time failure causes:

  • StepType not imported / wrong Type name in the workflow
  • Provider alias referenced by a step is missing in $providers
  • Template paths resolve to null (missing request data)

Use the step results and event messages to locate the failing step quickly.
