Could you please share the fix? I am facing a similar error while trying to build the UnrealHeaderTool

Ok, I have figured out the fix. You may notice in the logs something like node is missing or not installed (I do not remember the exact wording). What you need to do, extract the version from the path and do a full search, you will find a reference to this version in one of *.cs files. You need to update the version to the correct version. The correct version you can just find as a directory name.

In my case I needed to update this file:

I can corroborate the missing NODEJS issue. And this seems to be the reasonable solution if you are still trying to build the engine from scratch.

I have opted to downgrade to Engine Version 4.23.1 because, when I finished the build, I was simply redirected to the UE4-HTML Docs.

I will probably avoid the HTML package route and simply create native apps (desktop/mobile) instead. Why?:

• How am I going to keep updating my project version of the engine later on? This solution forces you to build the engine from the scratch and I am not savvy enough to even consider updating this later on the road at the current stage of my project.

• UE4 Core engine has already moved this to a CE fully. Meaning that it wont bring it to UE5.

• HTML package exports are simply way to heavy for a web app. WASM and data files can take up to a gigabyte. Transferring that from an static server S3. Will take time and is a very painful load for users.
