API didn't return flow's output if there's a subflow in the flow

[razuro]

Describe the issue

Hi Team,

I'm using the API http://localhost:8080/api/v1/executions/company.team/secondary_flow?wait=true Inside this flow, there's a subflow.

Expected API output: API will return the flow's output (named: secondary_flow)

Actual output: API return the subflow's output

Subflow

id: main_flow
namespace: company.team
tasks:
  - id: primary
    type: io.kestra.plugin.core.debug.Return
    format: Hello

outputs:
  - id: main_output
    type: JSON
    value: |
      {
        "main_output": {{ outputs.primary }}
      }

The flow that called the main flow

id: secondary_flow
namespace: company.team
tasks:
  - id: call_main_flow
    type: io.kestra.plugin.core.flow.Subflow
    namespace: company.team
    flowId: main_flow
    wait: true

outputs:
  - id: secondary_output
    type: JSON
    value: |
      {
        "secondary_output": {{ outputs.call_main_flow }}
      }
