Empty in workflow

[Keyu-1218]

Hi! Thank you for the amazing job!
I connect TDComfyUI with workflow_api, however there is no content show in workflow, even I use the example you provide. Sometimes it shows workflow destroyed, can you help me with this?

i have the same problem T.T

I have the same problem, TD ver. 2023.11600

I am experiencing the same issue with an empty workflow in the TD properties.
Occasionally the KSampler seed is visible.

TD 2023.12120
ComfyUI v0.3.10
ComfyUI-Manager v2.55.5
ComfyUI Nodes for External Tooling

same issue :(

Might be version mismatch. Solution should be update ComfyUI with manager or download latest.

[phattiej]

Should be the latest version of comfy installed because I just installed today and UI is different from the tutorial video, then made all the updates. I installed ComfyUI manager using git in command prompt. But I'm using TouchDesigner 2023, would that be an issue?

You might need to export workflow in API format with your ComfyUI version.

[phattiej]

I had done that. I also did it again just to be sure ^^, then when I connected the workflow dat to the tox it said workflow destroyed. Still getting the same problem. It shows one slider called ksampler seed.

FWIW, this on MacOS 15.2.

I have found that whichever input is defined first in the API export, will show up as the
only par in TD ... likely due to the following error I noticed in TD.

Issue appears to be when trying to add the workflow pars in TD?

I uncommented 195-198 in TDcomfyEXT, which shows the single workflow variable that was added as a TD par.

    print(jsonPar)
    print(class_title)
    print(inputs[i])
    print(i)

    [['sd3.5_medium.safetensors', 'sd3_medium.safetensors', 'sd3_medium_incl_clips_t5xxlfp16.safetensors', 'sd_xl_base_1.0.safetensors', 'sd_xl_refiner_1.0.safetensors',   'v1-5-pruned-emaonly.safetensors', 'v2-1_768-ema-pruned.safetensors'], {'tooltip': 'The name  of the checkpoint (model) to load.'}]
    Load Checkpoint
    sd3_medium_incl_clips_t5xxlfp16.safetensors
    ckpt_name

I added a print(data) in the TDcomfyEXT load(self) callback function (line 158).

    jsonData = json.loads(data)
    print(data)

. . . cut . . .
{"default": 0, "min": 0, "max": 16384, "step": 8}], "top": ["INT", {"default": 0, "min": 0, "max": 16384, "step": 8}], "right": ["INT", {"default": 0, "min": 0, "max": 16384, "step": 8}], "bottom": ["INT", {"default": 0, "min": 0, "max": 16384, "step": 8}], "feathering": ["INT", {"default": 40, "min": 0, "max": 16384, "step": 1}]}}, "input_order": {"required": ["image", "left", "top", "right", "bottom", "feathering"]}, "output": ["IMAGE", "MASK"], "output_is_list": [false, false], "output_name": ["IMAGE", "MASK"], "name": "ImagePadForOutpaint", "display_name": "Pad Image for Outpainting", "description": "", "python_module": "nodes", "category": "image", "output_node": false}, "EmptyImage": {"input": {"required": {"width": ["INT", {"default": 512, "min": 1, "max": 16384, "step": 1}], "height": ["INT", {"default": 512, "min": 1, "max": 16384, "step": 1}], "batch_size": ["INT", {"default": 1, "min": 1, "max": 4096}], "color": ["INT", {"default": 0, "min": 0, "max": 16777215, "step": 1, "display": "color"}]}}, "input_order": {"required": ["width", "height", "batch_size", "color"]}, "output": ["IMAGE"],

The data variable appears to be cut short, as it terminates with a ,.

I get this same result when testing different Comfy workflows.

I do get a complete json object with wget http://127.0.0.1:8188/object_info. The output json object is ~205KB.

I am currently trying to understand how the callback functions work and where the issue might lie. ... it's my first time diving into callbacks ...

Also ... I can execute the workflows without issue, and the generated image does show up in TD.
It is just an issue with parsing the Workflow variables to TD pars.

I tried what you did and uncommented out the lines 195-198, then I added the line on 158 and I got an error but with the websockets. Though I'm running on windows

[jx666jx]

Open a textport window to see the print and initial errors when attaching a workflow.

FYI ... updating to ComfyUI version 1.0.8 fixed the issue for me.

Thanks @olegchomp!!!

I did the same just now. Updated ComfyUI, re-added the TD component, and everything started working. It's working great! It's a bit slower streaming than the stream diffusion component. But happy it works. Thanks @olegchomp !
