Is this a bug in the Forge API?

Shuffle Controlnet works when running in Forge UI, but it doesn't work when running in Forge API（No error reported, but it has no effect）. Is this a bug in the Forge API?

By the way, it also works in the A1111 API, but not in the Forge API. The code is as follows:

{
'enabled': True,
'image': encoded_image,
'module': 'shuffle',
'model': 'control_v11e_sd15_shuffle_fp16 [04a71f87]',
'weight': 2,
'resize_mode': 0,
'lowvram': False,
'processor_res': 512,
'threshold_a': 64,
'threshold_b': 64,
'guidance_start': 0,
'guidance_end': 1,
'control_mode': 2,
'pixel_perfect': False
}

Start with the Forge API handling for the supplied ControlNet payload and compare it with the A1111 API behavior described in the issue. Reproduce the request using the shown `shuffle` configuration; done means the Forge API produces an output affected by Shuffle ControlNet or clearly reports why it cannot.
