pick() always will return an array even for multiselect === true even if the TypeScript typing is tuned to claim this different.

In my NC instance the calendar attachments do not work, as this uses the file-picker in single-select mode, however, looking at the following line of code in the dialogs package

nextcloud-dialogs/lib/filepicker-builder.ts

Line 103 in 961a4d0

return nodes.map((node) => node.path) as (IsMultiSelect extends true ? string[] : string)

reveals that pick() always will return an array of strings (JS Array.map() will return an array, there is nothing to argue about), but the TS types in that line are tuned to lie about this fact.

The return value in the transpiled code will always be an array. So either the TS type-hints should be adjusted accordingly, or the code should be fixed to act as intended.

Ah yes seems like a regression of 6.2.0
