It appears the Geonode Shape Key addon has not been updated for Blender 4. In Blender v4.0.2 with GNSK v0.0.4, saving a file with a default cube and then linking the cube and attempting to add a shape key produces the following error message:

Python: Traceback (most recent call last):
  File "C:\Users\****************\AppData\Roaming\Blender Foundation\Blender\4.0\scripts\addons\geonode_shapekeys\operators.py", line 158, in execute
    mod.node_group = link_shape_key_node_tree(context)
  File "C:\Users\****************\AppData\Roaming\Blender Foundation\Blender\4.0\scripts\addons\geonode_shapekeys\operators.py", line 71, in link_shape_key_node_tree
    with bpy.data.libraries.load(blend_path, link=do_link, relative=True) as (data_from, data_to):
OSError: load: C:\. failed to open blend file

Changing the filepath in the preferences to point to the blend file included with the addon then produces this message:

Python: Traceback (most recent call last):
  File "C:\Users\****************\AppData\Roaming\Blender Foundation\Blender\4.0\scripts\addons\geonode_shapekeys\operators.py", line 169, in execute

  File "C:\Users\****************\AppData\Roaming\Blender Foundation\Blender\4.0\scripts\addons\geonode_shapekeys\operators.py", line 20, in geomod_set_param_value
    input_id = geomod_get_identifier(modifier, param_name)
  File "C:\Users\****************\AppData\Roaming\Blender Foundation\Blender\4.0\scripts\addons\geonode_shapekeys\operators.py", line 11, in geomod_get_identifier
    input = modifier.node_group.inputs.get(param_name)
AttributeError: 'GeometryNodeTree' object has no attribute 'inputs'

I assume this is related to the recent refactoring of the API: https://wiki.blender.org/wiki/Reference/Release_Notes/4.0/Python_API#Node_Groups

Using the same file with Blender 3.6 works as expected.

Hi,

Are you still having this issue? Also if the bug is related to a specific blender version please provide the hash for that version of blender from the About Blender pop-up.

No, because I fixed it myself.

Like I said, the script files need to be updated to account for the API changes in 4.0.

def geomod_get_identifier(modifier: bpy.types.Modifier, param_name: str) -> str:
    
    # 3.x
    # input = modifier.node_group.inputs.get(param_name)

    # 4.0
    input = modifier.node_group.interface.items_tree[param_name]

    if input:
        return input.identifier

I've already patched my own script files, and it's been over a month, so I don't remember what other corrections need to be made.
