Error when generating initial mapping

[smessier1234]

I'm receiving the following error when running the migrator:

ForEach-Object : You cannot call a method on a null-valued expression.
At C:\Users\steven.messier\Downloads\FlowPowerAppsMigrator\GenerateInitialMapping.ps1:16 char:10

• $lists | ForEach-Object {

•      ~~~~~~~~~~~~~~~~
  

  • CategoryInfo : InvalidOperation: (:) [ForEach-Object], RuntimeException
  • FullyQualifiedErrorId : InvokeMethodOnNull,Microsoft.PowerShell.Commands.ForEachObjectCommand

I've looked at the PowerShell script and I can't tell what null value it's referencing. I've verified the URLs for the target and source are correct.

Hi @smessier1234,

Perhaps, $lists is null because connection to the source SharePoint online site failed.

Can you tell me more about this issue, please?

• Did you see a login prompt for the source site?
• Did you see any other errors before you got the error you posted?

I've also just published a new release with some bug fixes. Maybe you can try a new version?

The login prompt pops up and authenticates with my company's SSO. I didn't see any other errors. The issue seems to be with one site since I get farther along in the process if I try entering another source URL. I'm an owner of the source site, so I don't think it would be a permissions issue.

I tried using the latest version you published, but I received the same error about a null-valued expression.
