Samplers seem to be broken after ComfyUI update

[fidecastro]

Just updated my ComfyUI install and it seems the samplers are broken. Any samplers I attempt to use don't work, although the issues differ depending on the sampler I try.

The error below shows up trying to use Euler Ancestral:

Error occurred when executing KSamplerAdvanced:

Can you give me your workflow? If you have custom nodes installed move them and try without them.

sampler_issue_workflow.json

Here it is. I'm killing the custom nodes and will report back

[fidecastro]

Just tested and things seem to work if I kill the SimpleMath nodes that define total steps.

also experiencing ksampler errors as of couple hours ago

[fidecastro]

@Brotoshi do you know if you were using a custom node called SimpleMath?

It appears that something happened in my workflow after I updated comfy that broke its connections in the JSON workload file from one ComfyUI commit to another.

Hey hey, nah I don't have the SimpleMath node anywhere, but sure its one of the custom nodes - my other workflows are working fine. The workflow in question is below; https://civitai.com/models/151906/sdxl-qr-code-art-generator

[sborys-ai]

A similar error occurs, before the last update the workflow was working fine. There is a nuance, I am using two KSampler nodes and when using certain Checkpoint models, the process crashes on the first KSampler, when using other models it crashes on the second, I can't understand the dependency yet... SimpleMath node is not installed in ComfyUi.

I have exactly the same issue here. And the same solution.

For those who were previously using Efficiency nodes, please remove the existing efficiency nodes and reinstall Efficiency Nodes for ComfyUI Version 2.0+.

Please report any issues that occur with Efficiency nodes at https://github.com/jags111/efficiency-nodes-comfyui.

For those who were previously using Efficiency nodes, please remove the existing efficiency nodes and reinstall Efficiency Nodes for ComfyUI Version 2.0+.

This solution worked for me. Exactly as per the pic, removed and installed in Comfy Manager.
