FBX export operator - How can I change the scaling mode?

Question

I want to change the scaling mode in blender

based on documentation I can do it:

apply_unit_scale

apply_unit_scale (boolean, (optional)) – Apply Unit, Take into account current Blender units settings (if unset, raw Blender Units values are used as-is)

apply_scale_options

apply_scale_options (enum in ['FBX_SCALE_NONE', 'FBX_SCALE_UNITS', 'FBX_SCALE_CUSTOM', 'FBX_SCALE_ALL'], (optional)) –

I tried to change the scaling mode to unit scaling in blender but I don't know why it didn't work

import bpy
bpy.ops.export_scene.fbx(apply_unit_scale=True)
bpy.ops.export_scene.fbx(apply_scale_options='FBX_SCALE_UNITS')

I have this error in the console:

I also tried to copy and paste the example in the console but I have same error!:

bpy.ops.export_scene.fbx(filepath="", check_existing=True, filter_glob="*.fbx", use_selection=False, use_active_collection=False, global_scale=1.0, apply_unit_scale=True, apply_scale_options='FBX_SCALE_NONE', bake_space_transform=False, object_types={'ARMATURE', 'CAMERA', 'EMPTY', 'LIGHT', 'MESH', 'OTHER'}, use_mesh_modifiers=True, use_mesh_modifiers_render=True, mesh_smooth_type='OFF', use_subsurf=False, use_mesh_edges=False, use_tspace=False, use_custom_props=False, add_leaf_bones=True, primary_bone_axis='Y', secondary_bone_axis='X', use_armature_deform_only=False, armature_nodetype='NULL', bake_anim=True, bake_anim_use_all_bones=True, bake_anim_use_nla_strips=True, bake_anim_use_all_actions=True, bake_anim_force_startend_keying=True, bake_anim_step=1.0, bake_anim_simplify_factor=1.0, path_mode='AUTO', embed_textures=False, batch_mode='OFF', use_batch_own_dir=True, use_metadata=True, axis_forward='-Z', axis_up='Y')

You can. However, you would have to specify a valid file path in order to make it work. — brockmann, Aug 23 '20 at 16:33
You need to set the file path where you want to store the output. — Robert Gützkow, Aug 23 '20 at 16:33

oh sorry for this stupid question as Robert Gützkow and brockmann mentioned I didn't set the path

import bpy
#example path to store files
path = os.path.expanduser("~/Desktop")
#export fbx
filename = path + 'Test.fbx'
bpy.ops.export_scene.fbx(filepath=filename, use_selection=True,apply_scale_options='FBX_SCALE_UNITS',apply_unit_scale=True)

os.path.join() method in Python join one or more path components intelligently. This method concatenates various path components with exactly one directory separator (‘/’) following each non-empty part except the last path component. If the last path component to be joined is empty then a directory seperator (‘/’) is put at the end.

import bpy
importing os module
import os
#example path to store files
path = os.path.expanduser("~/Desktop")
Join various path components
filename = os.path.join(path, 'Test.fbx')
bpy.ops.export_scene.fbx(filepath=filename, use_selection=True,apply_scale_options='FBX_SCALE_UNITS',apply_unit_scale=True)

Instead of setting path manually, I use this solution

Recommend use os.path.join() or have a look into pathlib if you haven't already. – brockmann Aug 23 '20 at 16:47
@brockmann thank you. I actually don't want to set the path manually is there a way to set the path by the browser for export_scene.fbx? – Seyed Morteza Kamali Aug 23 '20 at 17:01
Pass "INVOKE_DEFAULT" as first argument. See Execution Context in the API docs. This will open the file browser with the settings applied, but you still need to select the location. – Robert Gützkow Aug 23 '20 at 17:02
Depends how the UI should look like and where do you want to have it. In general such basic questions have an answer here already, just search for it or explain in detail what you'd like to get and why other answers are bad @SeyedMortezaKamali – brockmann Aug 23 '20 at 17:05
