Error: Generation has thrown an exception: IDProperty "warp" does not support UI data

Note: warp is the name of my custom property. It's not used, just registered, so the custom properties panel displays it as an empty dictionary {}

Exact steps for others to reproduce the error
Register a custom property to pose bones, read the property in one of the metarig bones, then generate rig.

Run this script, to do that (go into pose mode of a metarig first):

import bpy

class Custom_Prop(bpy.types.PropertyGroup):
    pass

bpy.utils.register_class(Custom_Prop)
bpy.types.PoseBone.custom_prop = bpy.props.PointerProperty(type=Custom_Prop)

print(bpy.context.active_pose_bone.custom_prop)  # Adds the API defined entry into the bone's custom properties

bpy.ops.pose.rigify_generate()
