Errors in Blender 4.2

[supertobi]

Hello,

I know this is an old script, and there was no development in the last years. But I like it and perhaps you could look into this error with the Blender version 4.2:

Btw. most of the script works "just" the colors are not there:

And the I have even a feature request. Would it be possible to load two images. One for the hight ond one for the color.

I replace this code

def color_block_mesh(context, props, colors: List[list]):
    bpy.ops.mesh.vertex_color_add()
    layer = context.object.data.vertex_colors[0].data

    i = 0
    for row in colors:
        for color in row:
            for _ in range(24):  # 6 faces, 4 vertices each
                layer[i].color = color
                i += 1

with this one, what do you think, is that the right solution?

def color_block_mesh(context, props, colors: List[list]):
    # Ensure we are in Object Mode before making changes
    bpy.ops.object.mode_set(mode='OBJECT')

    # Get the active object
    obj = context.object
    
    # Check if the object is a mesh
    if obj and obj.type == 'MESH':
        # Create a new vertex color layer if it doesn't exist
        if not obj.data.vertex_colors.get("Col"):
            obj.data.vertex_colors.new(name="Col")

        # Access the vertex color layer
        layer = obj.data.vertex_colors["Col"].data
        
        i = 0
        for row in colors:
            for color in row:
                for _ in range(24):  # 6 faces, 4 vertices each
                    layer[i].color = color
                    i += 1
    else:
        print("Active object is not a mesh.")

I think the same change needs to be done for color_plane_mesh

I created a PR to fix this issues. please review
