Failed to call GetHistoryItems

[segrey]

I would like to run a small init script before a PowerShell session starts to access PSReadLine command history there. Unfortunately, [Microsoft.PowerShell.PSConsoleReadLine]::GetHistoryItems() fails with error.

powershell.exe -NoExit -ExecutionPolicy Bypass -File .\init.ps1

#init.ps1
if (Get-Module -Name PSReadLine) {
  $HistoryItems=[Microsoft.PowerShell.PSConsoleReadLine]::GetHistoryItems()
  if ($HistoryItems -eq $null) {
    [Console]::WriteLine("got null")
  }
  else {
    [Console]::WriteLine("got not-null")
  }
}

Result:

PS C:\Users\serge\sandbox> powershell.exe -NoExit -ExecutionPolicy Bypass -File .\init.ps1

Try the new cross-platform PowerShell https://aka.ms/pscore6

Exception calling "GetHistoryItems" with "0" argument(s): "Object reference not set to an instance of an object."

got null

Any idea what can be wrong? Thanks!

If I run the same script inside PowerShell session, GetHistoryItems() works fine.
