[BUG] Copy-PnPFileMetadata returns error "Copy-PnPFileMetadata: You are not signed in. Please use Connect-PnPOnline to connect."

[Benjy-MTB]

Please confirm what it is that your reporting
Since updating PowerShell to v.7.6.3, the commandlet Copy-PnPFileMetadata has stopped working as expected.

Expected behavior

Commandlet should copy file metadata from the source to the destination

Actual behavior

The script I've been using was working fine last week, but is no longer working since updating to Powershell 7.6.3.

Error message:
"Copy-PnPFileMetadata: You are not signed in. Please use Connect-PnPOnline to connect."

Steps to reproduce behavior

PS /Users/ben-mba> Update-Module PnP.PowerShell
PS /Users/ben-mba>
PS /Users/ben-mba> $SourceSiteUrl = "https://redacted.sharepoint.com/sites/2021ProjectsandProposal" PS /Users/ben-mba> $TargetSiteUrl = "https://redacted.sharepoint.com/sites/Masterprojectdatabase"
PS /Users/ben-mba>
PS /Users/ben-mba> # Site-relative source library root
PS /Users/ben-mba> $SourceLibraryRootSiteRelative = "Shared Documents"
PS /Users/ben-mba>
PS /Users/ben-mba> # Server-relative source library root
PS /Users/ben-mba> $SourceLibraryRootServerRelative = "/sites/2021ProjectsandProposal/Shared Documents"
PS /Users/ben-mba>
PS /Users/ben-mba> # Site-relative destination folder in the target site
PS /Users/ben-mba> $TargetFolderSiteRelative = "Shared Documents/2021 Projects and Proposals"
PS /Users/ben-mba>
PS /Users/ben-mba> # Server-relative destination folder, used by Copy-PnPFile
PS /Users/ben-mba> $TargetFolderServerRelative = "/sites/Masterprojectdatabase/Shared Documents/2021 Projects and Proposals"
PS /Users/ben-mba>
PS /Users/ben-mba> $sourceConn = Connect-PnPOnline `

-Url $SourceSiteUrl -Interactive
-ClientID "redacted" -ReturnConnection PS /Users/ben-mba> PS /Users/ben-mba> $targetConn = Connect-PnPOnline
-Url $TargetSiteUrl -Interactive
-ClientID "redacted" -ReturnConnection PS /Users/ben-mba> PS /Users/ben-mba> Write-Host "Copying standard metadata recursively..." Copying standard metadata recursively... PS /Users/ben-mba> PS /Users/ben-mba> Copy-PnPFileMetadata
-SourceUrl $SourceLibraryRootSiteRelative -TargetUrl $TargetFolderSiteRelative
-SourceConnection $sourceConn -TargetConnection $targetConn
-Force -Verbose VERBOSE: Cmdlet execution started for Copy-PnPFileMetadata

Copy-PnPFileMetadata: You are not signed in. Please use Connect-PnPOnline to connect.
PS /Users/ben-mba>

Checking Entra shows that the Connect-PnPOnline sign-ins are successful, and this is reinforced by the fact that I can successfully copy the files / folders between the two sites immediately prior to trying to copy the metadata.

What is the version of the Cmdlet module you are running?

(you can retrieve this by executing Get-Module -Name "PnP.PowerShell" -ListAvailable)
Version 3.2.0

Which operating system/environment are you running PnP PowerShell on?

MacOS

Seems like an issue with your script , maybe try updating to the latest version of PnP PowerShell and try ? Also, maybe uninstall old versions of PnP PowerShell , sometimes it loads older versions , cant repro

Thanks, I have tried all of that, deleted 3.2.0 and installed 3.3.0 clean. Still having the same problem.
I tested the script on another Sharepoint site migration (part of the same project), and I was able to copy the files using PnP just fine. The error only arises when I subsequently try to copy the metadata.

Just checked the code snippet, you also need to specify -Connection $sourceConn parameter as well in Copy-PnPFileMetadata since you are using -returnconnection in connect-pnponline, maybe try with that

Thanks so much Gautam, it took me a while to get around to trying this, but that did indeed turn out to be the problem!
The documentation for this commandlet needs to be updated, as you can see Example 5 is the relevant one here, and it doesn't include the requirement to specify the -Connection parameter after -returnconnection:
