Help! Export Flows with PnP

[jutrust]

Hello! This is my first post, and I need some help.
I've been trying to export my tenant's Power Automate flows via Export-PnPFlow. I have a few hundred flows, so doing it by hand isn't really feasible.
The script works well enough for some flows, but is throwing an error for others, but I can't see why.
It does not seem to be caused by if it's enabled/disabled, owned by a certain user, or in/out of a solution.
The ones that work, work perfectly; the others give the following error:

Export-PnPFlow : {"error":{"code":"ConnectionAuthorizationFailed","message":"The caller object id is '08#####-#####-####-###'. Connection '2#####-#####-####-####' to 'shared_logicflows' cannot be used to activate this flow, either because 
this is not a valid connection or because it is not a connection you have access permission for. Either replace the connection with a valid connection you can access or have the connection owner activate the flow, so the connection is shared with you in the context of 
this flow."}}
At C:\Users\jutrust\script.ps1:13 char:21
+ ...             Export-PnPFlow -Environment $environment -Identity $flow. ...
+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Export-PnPFlow], HttpRequestException
    + FullyQualifiedErrorId : System.Net.Http.HttpRequestException,PnP.PowerShell.Commands.PowerPlatform.PowerAutomate.ExportFlow
 

My question is, is it possible that these flows are deleted and that's why I get this error? If so, how can I check?
Code below.

 Connect-PnPOnline -url https://########.sharepoint.com
 $environments = get-pnppowerplatformenvironment
 foreach($environment in $environments)
    {
        $flows = Get-PnPFlow -Environment $environment -AsAdmin 
        foreach ($flow in $flows) 
            {
                    $filename = $flow.Properties.DisplayName.Replace(" ", "")
                    $timestamp = Get-Date -Format "yyyymmddhhmmss"
                    $exportPath = "$($filename)_$($timestamp)"
                    $exportPath = $exportPath.Split([IO.Path]::GetInvalidFileNameChars()) -join '_'
          
                    Export-PnPFlow -Environment $environment -Identity $flow.Name | Out-File "C:\Users\jutrust\documents\$exportPath.json"
           }
     }

*Edit: Corrected error message
