System Information
Operating system: Windows-10-10.0.17763 64 Bits
Graphics card: Intel(R) HD Graphics 530 Intel 4.5.0 - Build 25.20.100.6373

Blender Version
Broken: version: 2.81 (sub 16), branch: master, commit date: 2019-11-20 14:27, hash: blender/blender@26bd5ebd42
Worked: (optional)

Short description of error
In Compositor It's impossible to use extra outputs of Render Layers node via Python API.

Exact steps for others to reproduce the error
Sample code:

bpy.context.scene.view_layers['View Layer'].cycles.denoising_store_passes = True
bpy.context.scene.use_nodes = True
node_tree = bpy.context.scene.node_tree
target_nodes = node_tree.nodes
links = node_tree.links
for node in target_nodes:
    target_nodes.remove(node)
image_node = target_nodes.new(type='CompositorNodeRLayers')
denoiser_node = target_nodes.new(type='CompositorNodeDenoise')
image_to_denoiser_link_1 = links.new(image_node.outputs[0], denoiser_node.inputs[0])
image_to_denoiser_link_2 = links.new(image_node.outputs[4], denoiser_node.inputs[1])
image_to_denoiser_link_3 = links.new(image_node.outputs[5], denoiser_node.inputs[2])

Last two lines of code produce no result.

This currently works "as designed". Fortunately, it is not true that you cannot create these links currently. The issue is that your socket indices are wrong. The Render Layers node has a bunch of output sockets that are disabled currently (39 in my case). Currently, the "Denoising Normal" socket is actually at index 32. I recommend you just use the names of the sockets instead of their indices.

image_node.outputs["Denoising Normal"]
