What happened?

Dataview (for inline JS query 'dv.list(app.workspace.getLastOpenFiles().map(function(x){return(dv.page(x).file)}))'): TypeError: Cannot read properties of undefined (reading 'file')

DQL

No response

JS

$=dv.list(app.workspace.getLastOpenFiles().map(function(x){return(dv.page(x).file)}))

The request has worked once, but do not work anymore ...

For info the following request is working well

`$=dv.page(app.workspace.getLastOpenFiles()[0]).file`

resulting in

path: 001-Home/lastViewed.md, folder: 001-Home, name: lastViewed, link: lastViewed, outlinks: <empty list>, inlinks: home, etags: <empty list>, tags: <empty list>, aliases: <empty list>, lists: <empty list>, tasks: <empty list>, ctime: 5:25 PM - avril 09, 2024, cday: avril 09, 2024, mtime: 6:53 PM - avril 09, 2024, mday: avril 09, 2024, size: 541, starred: false, frontmatter: <empty object>, ext: md

you are accessing the file property on an undefined object.
this is not a dataview issue.

try this:

`$=dv.list(app.workspace.getLastOpenFiles().map(path => typeof dv.page(path) + " - " + path))`

as you can see in my case, non-notes are not pages so obviously, dv.page will not return a page in said case.

what you CAN do, is this:

`$=dv.list(app.workspace.getLastOpenFiles().map(x=>dv.page(x)).filter(x=>x).map(x=>x.file))`
