dpapi::chrome "/unprotect" error

https://github.com/samratashok/nishang/blob/master/Gather/Invoke-Mimikatz.ps1

when i run this command
Invoke-Mimikatz -Command dpapi::chrome /in:"%localappdata%\Google\Chrome\User Data\Default\Login Data" /unprotect

I get an error for /unprotect so mimikatz will not decrypt the chrome file.
What am doing wrong?

error
`Invoke-Mimikatz : A positional parameter cannot be found that accepts argument '/unprotect'.

And if I run this command
Invoke-Mimikatz -Command '"dpapi::chrome /in:""%localappdata%\Google\Chrome\User Data\Default\Login Data"" /unprotect"'

I get this error
