supplied ValueFrom is ignoring default

[CodingOrca]

I try to implement an approve - release workflow, have a timeout on the approve step and be able to react if the timeout has expired.

The documentation of the SupppliedValueFrom:
https://argoproj.github.io/argo-workflows/fields/#suppliedvaluefrom
shows an example without a duration:
https://github.com/argoproj/argo-workflows/blob/master/examples/suspend-template-outputs.yaml

Is is working, but it is not of practical use if I have no duration set on the suspend Template. So I have modified it according to the documentation found here:
https://argoproj.github.io/argo-workflows/executor_swagger/#valuefrom

This is only the changed part of the example:

- name: approve
    suspend:
      duration: "60"
    outputs:
      parameters:
        - name: message
          valueFrom:
            default: "some default value"
            supplied: {}

If I run the workflow, and do not supply a value from outside, after 60 seconds the output printed by the "release" step is:
{{steps.approve.outputs.parameters.message}}

But I am expecting the "release" step to print:
some default value

If I feed a value to the parameter per REST API, and set it to e.g. "AP has approved this!", and then I resume the workflow - also per REST API in my case - the "release" step is, indeed, printing the value which have passed:
AP has have approved this!

What am I doing wrong?
I am using argo workflows v3.2.4

We fixed a related issue recently. Could you try upgrading to v3.3.0-rc4?

Thanks for your so fast reaction!
I have upgraded to v3.3.0-rc4, and unfortunately nothing changed!
If I provide the parameter value from outside, the input parameter of the release step is filled in correctly.
But if the delay expires and the workflow resumes automatically, the input parameter of the release task simply has the literal value of what is written in the template, including the curly brackets:
{{steps.approve.outputs.parameters.message}}

I believe this is an important point in workflows of this kind, which are waiting for an external value to be supplied, but need a default to go on with, if the timeout expires.

What I need is a way to check in the next step if there was an answer supplied from outside or if the step finished due to the timeout. Because depending on this I decide what to do next: release, send another email, or fail the workflow.

Hey, is there's a fix to the problem, Im also trying to pick a default value if the suspend timeout, but it does not evaluate the expression in that case...
is there any workaround?

This should have been fixed in v3.6.0: #12960

Correction: it's not in v3.6.0 yet, but it is in the release branch for 3.6: https://github.com/argoproj/argo-workflows/commits/release-3.6

So it should be in v3.6.1 when that's released
