**System Information** Operating system: Windows-10-10.0.19044-SP0 64 Bits Graphics card: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 496.76 **Blender Version** Broken: version: 3.1.0 Beta, branch: master, commit date: 2022-02-07 22:08, hash: `rB229d0ace026f` Worked: (newest version of Blender that worked as expected) **Short description of error** When object A, containing a GN node network, which outputs Face Corner attribute called "UVMap", references object B through the Object Info node, and the object B has UVMap channel called "UVMap", either applying the GN modifier on object A or converting object A to mesh using bpy.ops.object.convert(target='MESH') operator will cause destruction of the Face Corner attribute called "UVMap". This may be a regression, although I am not sure. **Exact steps for others to reproduce the error** 1. Open the attached .blend file: {F12855201} 2. Select the "Object_with_UVMap_Attribute" and note the GN modifier outputting "UVMap" attribute 3. Apply this GN modifier Result: The UVMap attribute is destroyed Expected: The UVMap attribute appears in the attribute list OR: 1. Open the attached .blend file: {F12855201} 2. Select the "Object_with_UVMap_Attribute" and note the GN modifier outputting "UVMap" attribute 3. Convert "Object_with_UVMap_Attribute" to a mesh using bpy.ops.object.convert(target='MESH') operator Result: The UVMap attribute is destroyed Expected: The UVMap attribute appears in the attribute list
