Get-PASSafeMember errors when adding parameter MemberName

[matiya]

Describe the issue

Running the command: Get-PASSafeMember -SafeName ABC-001

Returns all safe members as intended, for example:

UserName                        SafeName                    Permissions
--------                        --------                    -----------
vaultadmin01                    ACB-0001         @{useAccounts=True; retrieveAccounts=True; listAccounts=True; addAccounts=True; updateAccountCo…

With the -search parameter it works too:

Get-PASSafeMember -safe ABC-001 -search vaultadmin01

UserName     SafeName                    Permissions
--------     --------                    -----------
vaultadmin01 ABC-0001        @{useAccounts=True; retrieveAccounts=True; listAccounts=True; addAccounts=True; updateAccountContent=True; updateA…

But if I add the parameter -MemberName, for instance: Get-PASSafeMember -SafeName ABC-0001 -MemberName vaultadmin01

I get the following error:

MethodInvocationException:
