Get-PnPMicrosoft365GroupMembers show error but works

[Ofer-Gal]

In my script I use:
$members = Get-PnPMicrosoft365GroupMembers -Identity $m365Group.Id
It shows an error "Value cannot be null. (Parameter 'source')" but it works fine

$members contains a list of members as expected.
on the other hand
$owners = Get-PnPMicrosoft365GroupOwners -Identity $m365Group.Id shows no error at all and also works fine.
Just FYI

Thanks for grate Library
