[DEPRECATION WARNING] Error
I'm seeing the same error, it turns out to be because of the ComfyUI Manager using outdated APIs that no longer match the updated ComfyUI core files. They (ComfyUI Manager) need to update their files.
The warnings that are specific to ComfyUI-Manager of those are:
[DEPRECATION WARNING] Detected import of deprecated legacy API: /scripts/ui.js. This is likely caused by a custom node extension using outdated APIs. Please update your extensions or contact the extension author for an updated version.
[DEPRECATION WARNING] Detected import of deprecated legacy API: /extensions/core/groupNode.js. This is likely caused by a custom node extension using outdated APIs. Please update your extensions or contact the extension author for an updated version.
[DEPRECATION WARNING] Detected import of deprecated legacy API: /scripts/ui/components/buttonGroup.js. This is likely caused by a custom node extension using outdated APIs. Please update your extensions or contact the extension author for an updated version.
[DEPRECATION WARNING] Detected import of deprecated legacy API: /scripts/ui/components/button.js. This is likely caused by a custom node extension using outdated APIs. Please update your extensions or contact the extension author for an updated version.
as that's what comes up with ComfyUI-Manager as the only custom node.
The warnings that are specific to ComfyUI-Manager of those are:
To be more specific, the affected files are here:
ComfyUI\venv\Lib\site-packages\comfyui_frontend_package\static\extensions\core
ComfyUI\venv\Lib\site-packages\comfyui_frontend_package\static\scripts\ui
ComfyUI\venv\Lib\site-packages\comfyui_frontend_package\static\scripts\ui\components
And that package (comfyui-frontend-package==1.28.7) is part of ComfyUI's requirements.txt- file - not the Manager-custom-node. So this isn't a Manager problem, it should be addressed at the source of the requirements.txt- file: https://github.com/comfyanonymous/ComfyUI/
@GlamoramaAttack The depreciation warning is saying that those files are being imported and shouldn't be.
If you look through the js folder in ComfyUI-Manager, you'll notice import statements importing scripts/ui.js near the top of most of the files there.
As you can see here: https://github.com/comfyanonymous/ComfyUI/issues/10408
Those files are going to eventually be removed, which will break ComfyUI-Manager if this isn't taken care of before then.
@arcum42 Thanks for pointing that out. I obviously misunderstood something.
@GlamoramaAttack No problem. One or two of them were being reported erroneously, which is what that issue was fixing, but the rest weren't, and I'd already done a bit of testing to figure out which nodes I had installed were causing the warnings. There were several, but the warnings from this one make it hard to tell which other ones also cause the warning, since this is usually installed.
So far, the ones that can trigger the same warning are: ComfyUI-Manager ComfyUI-Crystools ComfyUI-Custom-Scripts ComfyUI-DD-Translation ComfyUI-Impact-Pack ComfyUI-VideoHelperSuite rgthree-comfy

This was after I went in to the Manager. Under "Installed", Manager was the only entry and the only command available was "Try Update" and no option to uninstall. This yielded same results of Deprecation Warnings. The only other alternative would be to delete the Manager folder from custom nodes. I forgot to mention that before I did all of this, I had installed the WAS Node (revised) which showed installed successfully in the CLI (which it hadn't done in my former installation which always stated (Import failed) no matter which one I tried to install. With this "new" installation it did so but failed to show up in the Settings portion anyway so no adjustments could be made to it.
With all due diligence to all the developers of this unique and wonderful program and the node developers, thank you for all your work! I think I started using ComfyUI a few months before the Flux models appeared. I try not to look gift horses in the mouth, mind you. But I do seem to be spending more time fixing things than generating things. I guess the proliferation of hundreds of models, it's hard to keep things sorted out with Python versions, Desktop, Portable, old/new workflows that have node incompatibilities, etc. I did finally figure out how to store my models on a separate drive just so I could re-install ComfyUI without having to re-download model gigabytes behind by using a fresh ComfyUI. And I hope this issue of Deprecation Warnings gets resolved especially since I don't use API's anyway. Still grateful, though!
Does anyone else get the ‘Failed to get custom node list.’ red error when trying to install missing nodes or even search for custom nodes?

As you can see from my post above, I was having all kinds of trouble. And installing some nodes like Was, InsightFace, et. al., would never work. In fact, I followed all kind of workarounds from YouTube for InsightFace for months and never could get it to install. This time I was getting annoyed with these failures so I kept the old ComfyUI Portable and reinstalled a new one. I did everything step by step keeping note of what worked and what didn't along the way. I found a package called "Easy Install" which also included separate .bat files one of which was "InsightFace" (Nunchaku & SageAttention was included also). ComfyUI now works and IF installed perfectly after all these months with the only errors being the deprecated legacy API stuff but I don't even use any API's anyway. So I can't tell you why the ComfyUI node list craps out on the "old" ComfyUI but it works just fine in the new! Maybe some Python issues complicated things during updates . . .
One more to report the deprecation warning in ComfyUI. Fresh portable installation, no errors. Installed ComfyUI manager, get deprecation warnings.
