Permission denied with glb saving with api_server only

[GarikDog]

Hello! I encountered a permission denied error while trying to work with the blender addon. Everything is fine with gradio_app itself, I can save and download meshes. But when working with api_server there is such a problem. I tried changing the temp location for the current session, I even tried running everything from the administrator from the general vs code debugging. Unfortunately nothing helped. I even tried to assign a temp folder inside the current conda environment directory. Always the same result.

I also tried to just directly create something in temp from the current terminal. It turns out to be possible to do this, that is, in theory there should be enough rights

On Windows devices, an opened file cannot be opened again for writing, but this is what is attempted on line 189 and 190, where NamedTemporaryFile opens the file and then mesh.export called from the next line tries to open it again for writing.

Change delete=True to delete=False on line 189 and add appropriate temp_file.Close() and os.unlink(temp_file.name) after the mesh is reloaded within that block.

Hope this helps.

Yes! Thank you! It works! Here is the block code, maybe it will help someone else!

with tempfile.NamedTemporaryFile(suffix='.glb', delete=False) as temp_file:
            mesh.export(temp_file.name)
            mesh = trimesh.load(temp_file.name)
            temp_file.close()
            os.unlink(temp_file.name)
            save_path = os.path.join(SAVE_DIR, f'{str(uid)}.glb')
            mesh.export(save_path)
