PipelineDeployStackAction:Stage xx already contains an action with name 'Execute'

[gmarchand]

I would want to use aws_cdk.app_delivery.PipelineDeployStackAction to deploy my multiple stacks cdk application but I have this error.
I can't modify the name of the action and I would want to use a stage per environment.

Reproduction Steps

My code:

app.py

...
baseline = BaseLineStack(app, f"{props['namespace']}-baseline", props)
middleware = MiddlewareStack(app, f"{props['namespace']}-middleware", props)
datastore = DatastoreStack(app, f"{props['namespace']}-datastore", props)

stacks = [baseline, middleware, datastore]
pipeline = PipelineStack(
    app,
    f"{props['namespace']}-pipeline",
    baseline.outputs,
    stacks)

pipeline_stack.py

      staging_stage = pipeline.add_stage(
            stage_name="deploy-staging",
        )
        order = 0


        for stack in stacks:
            order += 1
            s = app_delivery.PipelineDeployStackAction(
                input=build_app,
                admin_permissions=True,
                change_set_name=f"changeset-{stack.stack_name}",
                create_change_set_run_order=order,
                stack=stack,
            )
            staging_stage.add_action(s)
