Case: Unknown output node: lead the following error ----> v = G.nodes[node]['v'] KeyError: 'v'

[cihangoksu]

Hi,

I am trying to transpile a complex ComfyUI workflow. For some nodes in my workflow "node_pos_sum" function in init.py returns to 0 with a warning message. But that leads an error later on in the "visit" function in init.py

Is there a way to work around this KeyError caused by an empty node {} in ComfyScript?

Thank you in advance :-)

Cheers,
Cihan

Is the workflow you are transpiling in web UI format? If so, you can try to convert it to API format, i.e. load it in web UI and Save (API format) (enable dev mode in settings first), and then transpile again.

Hmm sorry how does it work with API format actually? I ran python main.py in ComfyUI folder, and then developed the workflow in my browser at http://127.0.0.1:8188/ , and then Clicked save to 'Save workflow as' Json. Then I transpiled as explained in Comfyscript tutorials:
python -m comfy_script.transpile PathToWorkflow.json

Enable Dev Mode in settings:

Then Save (API format):

Oh cool! I did not know that... Thx a lot :-) It solved the problem, but led another (as it' irrelevant, I am opening a new issue).

After saving a workflow in API format, I cannot run KSampler (Advanced) nodes without Model, +, - inputs? But it is not problematic in UI mode. Why is that? How can that be fixed?

[Chaoses-Ib]

Maybe some nodes break API format again. Are you using any UE Nodes?

[cihangoksu]

yes you are right sorry, anything anywhere and Prompts Everywhere nodes lose their connections, that is the problem.. Thanks for guiding through!
