Error when Library has no installed packages (v5.1.0)

[unborn-andy]

Hello .. excellent work keeping this useful node updated and with new features !

I get an error during NR startup that seems to be related to not having any packages installed with the node's Library.

29 Jun 04:00:26 - [error] TypeError: Cannot convert undefined or null to object

Software	Version
Node.JS	v16.14.0
npm	v8.8.0
Node-RED	v3.0.0-beta.3
uibuilder node	v5.1.0
uibuilderFE
OS	Windows 11

Many thanks for raising Andy.

If you need a work around, from a server command line:

// go to the uibRoot folder
cd ~/.node-red/uibuilder
// Install the dummy `aaa` package
npm install aaa --save
// restart node-red

That should do it.

I'll get a fix out ASAP.

Steve spotted a quick fix. In package-mgt.js at line 297:

        await Object.keys(lsParsed.dependencies).forEach( async pkgName => {
            await this.updIndividualPkgDetails(pkgName, lsParsed)
        })

change to

        await Object.keys(lsParsed.dependencies || {}).forEach( async pkgName => {
            await this.updIndividualPkgDetails(pkgName, lsParsed)
        })
