• [X] I can confirm the issues exists when I tested with :latest
• [ ] I'd like to contribute the fix myself (see contributing guide)

What happened/what you expected to happen?

Whenever we are calling the global output artifact in the exithandler Its failing with the error:

Bad Request: templates.exit-handler.steps failed to resolve {{workflow.outputs.artifacts.output-result-car}}

This error was introduced after upgrading to the v3.4.6,. Also have tested with v3.4.7, v3.4.8, v3.4.9, v3.4.10 same issue persist.

After downgrading to v3.4.5 same workflow is working without any issue

Version

Based on initial triage. GlobalArtifacts are not included in the scope to replace/substitute for the exit handler. Scope should populate the globalartifacts https://github.com/argoproj/argo-workflows/blob/f5e31f8f36b32883087f783cb1227490bbe36bbd/workflow/controller/operator.go#L3081

Any update on this?

An issue related to this one: the global output variables cannot be accessed in in exit handler either. Argo complains that {{workflow.outputs.parameters.global_variable_name}} cannot be resolved.

[omerlh]

Facing same issue as @Luobiny , are there any estimations to when this will be solved?
