How is throw handled during a for_each loop?

[e-gineer]

I have a for_each loop for an input step.

I'd like to run them in parallel, but stop waiting for inputs if any of them get a specific response (e.g. answer = deny).

How can I do that?

Current approach is to use a for_each and then throw { ... } when I get the deny. I expected that to break the for_each loop for me.

But - currently it seems to wait for each instance of the for_each to complete before breaking out based on the throw.

Should throw break the for_each loop? I believe an error/throw breaks execution if there are other parallel steps running, so I'd expect it to behave the same here?

  step "pipeline" "approve" {
    for_each = param.approvers

    pipeline = pipeline.single_approval

    args = {
      approver = each.value
      subject = param.subject
      prompt = param.prompt
      timeout = param.timeout
      default_decision = param.default_decision
    }

    throw {
      if = !result.output.approved
      message = "Approval failed"
    }

  }
