[BUG] Invoke-PnPBatch appending two forward slash which throws error invalid request

[onkaragarwal]

Hi
I am using PnP.Powershell 1.9.0 with PS 5.1.
Following is my command to connect-PnPOnline
$baseSiteUrlConnection=Connect-PnPOnline -Url $configureSiteUrl -ClientId $appId -ReturnConnection -Tenant $tenantId -Thumbprint $thumbprint
This connects successfully without any issue

$batch = New-PnPBatch

Following command is in loop
Set-PnPListItem -List $queueList -Identity $allDraftItems[$count+1].Id -Values @{([FieldNames]::Status)=([StatusFieldValues]::InProg)} -Batch $batch

When there is a single item then no issues but as it becomes multiple it throws Error "Invalid Request".
Upon inspection using fiddler I saw there are two forward slashes getting appended before api/web/lists...
This is causing the issue. If I edit the request and re run it using fiddler it works fine.
Can you please let me know what to do or how to skip that
