That isn't the node red log. Try
`sudo journalctl -f -n 100 -u nodered -o cat`

So looks like you are going from uibuilder v5 to v7 so do check out the breaking changes between them. 5 -\> 6 did have some changes that you need to deal with in your html file.

Quite likely the major node.js upgrade issue.

Make sure that you have the build tools installed so that npm can do rebuild of binary libraries for node.js.

It looks like this was the issue. In the jump from 6 to 7, I needed to switch from uibuilderfe.min.js to uibuilder.iife.min.js and remove socket.io.js. Thank you for this, it's running cleanly now.

I checked and I have it installed, it just doesn't seem to want to cooperate on cpufeatures. It looks like it still runs regardless, though.

Hopefully, the days of such issues are behind us now - at least for some while. The old client library is gone for good and the new library is much simpler to use. v7 cleared out a backlog of changes that might have been breaking for a few people. The next major upgrade is likely to only really have an impact on the minimum node.js version and will likely happen in line with Node-RED upgrading to v5.

Not sure if it is good to reply here but I am getting the exact same error:
`[error] [uibuilder:d997a40a5731934a] TypeError: fg.convertPathToPattern is not a function`
Upgraded the following:
Node-RED: v4.0.9 → v4.1.0
Node.js: v20.19.3 → v20.19.4
node-red-contrib-uibuilder@7.4.1 → 7.4.3
I already did the ‘npm rebuild’. In NodeRED it says “Configuring node” below the uibulder nodes and when I change something I am getting the Error ‘`fg.convertPathToPattern`' in the NodeRED Debug area. When I try to access the Website-URL I only get a ‘Cannot GET /website/’ message.
EDIT: I had to do the same thing to fix this issue:

> EDIT: for later readers, the initial issue was solved by making a copy of my uibuilder folder and exporting a copy of my uibuilder node (i only use one), then uninstalling uibuilder in Manage Palette, then using node-red-restart, then reinstalling uibuilder, then making a new uibuilder node as a near-exact copy of the old one (the only difference being an internal read-only version number variable used for debugging). After this, I was able to copy in my old html/css/js/image files and get the page to open again, but still had other issues tht were solved starting at the solution below.

You only need to rebuild when switching node.js major versions.

We really need to see more of the logs in order to make sense of them.

Do you mean in the Editor or in the node-red log - if in the Editor, if you expand the error message, we can get a full traceback of where the issue comes from.

Yes, uibuilder has not been able to mount your instance endpoint to ExpressJS.

I don’t really have enough to go on to be able to reproduce the error from what you’ve shared.

This error message was the only Error in ‘node-red-log’ when I started up NodeRED.

Whenever I changed something on the existing uibuilder-Node (e.g. just move it around and re-deploy) in the NodeRED Editor then the message that also mentioned something with an ‘fg.convertPathToPattern error’ appeared in the NodeRED Editor Debug window.
Unfortunately I didn’t expand this message and I directly went on to try the hint from the thread creator (remove and reinstall uibuilder), which fixed the error. 😆
Theres maybe one more interesting detail. If I now check the GIT version control history, there is only one single change for the uibuilder-node (that I imported back in my flow): deployedVersion was ‘5.1.1’ before and now “7.4.3”. Thats a bit strange as I was using uibuilder 7.4.1 before. Maybe just that variable didn’t get updated.
Anyway, everything is working again now. 🙂 It was just a bit strange, as I've never had to reinstall uibuilder after an update before.

OK, thanks for the update anyway.
That line of code was contributed by someone else and was merged in 3 weeks ago. It was a change to make the `fgSync` function in `fs.cjs` work correctly on Windows. It is only used in 1 place. The fgSync function is only called in 2 places in the `web.cjs` library. Once to add the instance API route (`//api/*.js`) and once to add any instance custom routes (`//routes/*.js`) - neither of which are commonly used by people.
Are you running on Windows or Linux?
