@YuriySamorodov - Your $list and your $folder are essentially the same? Or did you create a folder called "Shared Documents"? This is confusing because the Documents library is /Shared Documents in the background.

When I run the command with your values, I can reproduce the error. However, if you have created a folder yourself called "Shared Documents", then your -Identity should be "Documents/Shared Documents".
Have a look at the examples: https://pnp.github.io/powershell/cmdlets/Set-PnPFolderPermission.html

I have no issue otherwise when trying with 2.5.42.

Hi, @veronicageek . Shared Documents is the default Documents library. $list and $folder are the same, yes.

I submitted a PR at #4157 to change the error message. Set-PnPListPermission is probably what you should use to set permissions at list/library level.
