Did I do anything wrong?

Ah. You're naming the namespace HOUDINI. The correct namespace is “Houdini”. Uppercase “H”, lowercase “oudini”.
If you hover the mouse cursor over the particle attribute name, you can see the correct namespace.

I'm so stupid. Thank you very much for your help.

Even with that difference I'm still not getting an error on my side. I'm using the same version of 4.25, and set the namespace with “Change Namespace Modifer > Custom…”
Without a file or video showing the steps you're taking there's not much more I can do to help.

I tried to verify the error in this way.
Did I do anything wrong?
Thank you very much.

Any idea why this is happening?

I had the same problem.

Hmmmm. I've gone through my video and set that up again but it's not giving me any errors.

Is it only happening when you create a new module? What happens if you bypass that module in the stack? Is the HoudiniCache module input set correctly?

I seem to have found a mistake. The latest version I used: 4.25.0-13144385 + + + UE4 + release-4.25. In this version, the option of “namespace modifier add” is canceled. I can only add the subnamespace of Houdini through the “change namespacemodifier-custom” option. After modification, everything looks normal on the UI, but Niagara doesn't seem to know that this attribute is under houdinisubnamespace. I'm not sure if it's my mistake. I hope to get help. Thank you very much for your efforts.
I found the Houdini killifdead module you made, then I deleted the Houdini namespace of NID, and then I added the subnamespace of Houdini with the “change namespace modifier custom” option. Then the error occurred. The result of watching me add houdinnamespace on the UI is the same as before I delete your houdinnamespace
