Invoke-Sqlcmd with -NewPassword throws: Value cannot be null. (Parameter 'path2')

[BeniFreitag]

The documentation says -NewPassword can be used to change the password of a SQL Server Authentication login ID. When I run this Cmdlet it shows an error and it also changes the password:

Invoke-Sqlcmd -ServerInstance . -Username "TestLogin" -Password "OldPw" -NewPassword "NewPw"

Error: Invoke-Sqlcmd: Value cannot be null. (Parameter 'path2')

Exception Details:
