Errors installing uibuilder

General
1

I have a new installation of Node-red on a Raspberry 4b. On installing uibuilder, the uibuilder node is not available. I attempted to uninstall which gave an error: Failed to remove: node-red-contrib-uibuilder
Type in use: uibuilder

I then stopped Node-red and started it again. Noting the following on the log;

Welcome to Node-RED

Any help would be appreciated

This is the clue I think. I suspect that you did a Node-RED deploy without inputting a valid URL into your uibuilder node? If you correct that, it should start working.

Thanks for the reply. If I understand the process correctly, the way the URL is entered is by picking the uibuilder node and entering the URL into it's configuration. The problem for me in that immediatey following the install from Manage-pallete, there is no uibuilder node available.

OK. So now I tried completely removing node-red from my raspberry and reinstalled it. No errors.
I started node-red. Installed uibuilder. All OK!
Thank you.
