Error while installing custom_nodes: #332

Hello,
I'm trying to install the custom node: https://github.com/yolain/ComfyUI-Easy-Use

I am putting it in my model.json like this:
[
{
"url": "https://github.com/Suzie1/ComfyUI_Comfyroll_CustomNodes",
"path": "custom_nodes"
},
{
"url": "https://github.com/yolain/ComfyUI-Easy-Use",
"path": "custom_nodes"
}
]

However I get this error:
Cannot import /app/ComfyUI/custom_nodes/ComfyUI-Easy-Use module for custom nodes: No module named 'comfy.sampler_helpers'

Please help
