ConnectDrive not working in 3.1.0

[iainfm]

Hi,

I'm in the process of migrating a script from an old server to a new one, but I've run into a problem with the Connect-PnPOnline command that maps a drive to a sharepoint site. The command is:

Connect-PnPOnline -Url $siteUrl -ClientId $clientId -Tenant $tenantId -Thumbprint $thumbPrint -CreateDrive

The only thing that has changed between the old server and the new one is the thumbprint of the cert I'm using to connect. If I remove the -CreateDrive option it connects ok, but with it in use I get the error:

Connect-PnPOnline: Input string was not in a correct format. Failure to parse near offset 25. Expected an ASCII digit.

I've tried using -DriveName but I get the same error. This looks like a duplicate of #4717 but as far as I can tell the fix for this is still in place.

PnP.Powershell module is 3.1.0 and Powershell is 7.5.2. I feel like 3.1.0 has been around for long enough for this to have been noticed if it were a bug, so I'm a bit stuck.

Not sure whether to open an issue, or whether anyone can make a suggestion please.

Best wishes,
Iain
