System Information
Operating system: Windows 10
Graphics card: RTX 3080TI

Blender Version
Broken: 4.1
Worked: (newest version of Blender that worked as expected)

Short description of error
When applying tranforms via the search panel (f3 > apply all transforms) or via Object > Apply > All Transforms to an empty object (e.g. plain axis) the addon magic_uv will throw following python error:
Python: Traceback (most recent call last): File "A:\Programme\Windows\BlenderFoundation\4.1\4.1\scripts\addons\magic_uv\op\copy_paste_uv_object.py", line 149, in draw uv_maps = compat.get_object_uv_layers(obj).keys() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "A:\Programme\Windows\BlenderFoundation\4.1\4.1\scripts\addons\magic_uv\utils\compatibility.py", line 120, in get_object_uv_layers return obj.data.uv_layers ^^^^^^^^^^^^^^^^^^ AttributeError: 'NoneType' object has no attribute 'uv_layers'

When the addon magic_uv is disabled this error does not occur.
When applying transforms to an actual mesh this error does not occur.
When pressing ctrl + a > All transforms this error does not occur.
It doesn't matter what transform gets applied.
The error happens for all non-mesh object types, like empties or path based object with no actual mesh and thus no uv layers.
It has no effect on the applying transforms, it's just to some extent annoying to see some error message unrelated to the operation the user is performing.

Exact steps for others to reproduce the error
Based on the default startup .blend file.

Make sure the addon magic_uv is enabled and operational
Open the info editor to not miss the logged error in case it won't get displayed in the bottom bar.
Create an empty object (e.g. plain Axis)
With the empty selected: In the header of the 3d Viewport press Object > Apply > All Transforms
the Attribute error should now be logged in the info editor

Can confirm. Although it's best to submit to the addon repository.

Looks like somehow the menu draw call was called in Magic UV. That menu is only registered under VIEW3D_MT_object which is the viewport Object menu. Not sure what's going on...

Or maybe at https://projects.blender.org/extensions/magic_uv after the new extension migration. 🤔

Alright, moved the issue to the blender_addons repo: blender/blender-addons#105341

@PratikPB2123

Thanks for pinging me.
Do I have the commit right to the https://projects.blender.org/extensions/magic_uv/commits/branch/main ?
If so, I can commit my some patches to this repository instead of the blender-addons.

Maybe not... (https://projects.blender.org/org/extensions/members)
@dfelinto might know whether add-on owners already have the commit rights :)

Thanks @PratikPB2123 .

@dfelinto
Will I have a commit right to the extensions organization repository in future?
If no, how should I submit patches to the extension repository?

I've just written to @nutti to transfer the repository and the extension to him.
