Accessing step .main-logs in WorkflowTemplate no longer works after upgrade v3.4.11 to v3.4.12 #12065
Description
Pre-requisites
- I have double-checked my configuration
- 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?
We have workflow templates that reference as argument artifact inputs the .main-logs output artifact from the a previous step. This arrangement has been working well until a recent upgrade from v3.4.11 to v3.4.12 (same also occurs when upgrading to v3.5.x)
The HTTP400 error response content looks like this
{
"code":3,
"message":"templates.entrypoint-handler.steps failed to resolve {{ steps.foobar.outputs.artifacts.main-logs }}"
}The supplied sample workflow will work fine in v3.4.11 and prior but fail in v3.4.12 (and v3.5.x)
Version
v3.4.12
