System Information
Operating system: Linux-5.15.0-56-generic-x86_64-with-glibc2.35 64 Bits
Graphics card: NVIDIA GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 525.60.11

Blender Version
Broken: version: 3.4.1, branch: blender-v3.4-release, commit date: 2022-12-19 17:00, hash: 55485cb379
Worked: (newest version of Blender that worked as expected)

Short description of error
After created and initialized a new Node of type CompositorNodeOutputFile, I can't set the new node's base_path with either relative or absolute path. Suppose bpy script has the absolute path /home/home/heidi/blender_code. I want to save the generated normal png in the folder /home/home/heidi/blender_code/output/normal. But when I set the relative path to //output, Blender saves the normal images to the folder /home/home/heidi/blender_code/output/home/home/heidi/blender_code/output/normal.
The same result happens when I set base_path to the absolute path, i.e., /home/home/heidi/blender_code/output.

Exact steps for others to reproduce the error

bpy.context.scene.view_layers["ViewLayer"].use_pass_normal = choice
render_layers = bpy.context.scene.node_tree.nodes["Render Layers"]
normal_file_output = bpy.context.scene.node_tree.nodes.new(type="CompositorNodeOutputFile")
normal_file_output.label = 'Normal Output'
normal_file_output.name = 'Normal Output'
bpy.context.scene.node_tree.links.new(render_layers.outputs['Normal'], normal_file_output.inputs[0])
tree.nodes["Normal Output"].base_path = "//output"

I tested by simply setting the path to the path value for the node. Everything works. Please try to be more specific about your steps to reproduce the issue. Add descriptions, starting at the default cube...
