Talked Issue: Error: Attempt to read property "message" on null at nextcloud talk...

[kaushakya]

Greetings!
I have a Nextcloud (25.0.3) server and I tried setting up the Talked server on another AWS VM (Ubuntu 20.04.3 LTS) following the procedure at: https://github.com/MetaProvide/talked. When I am using the command "/recording start" in a chat room, I am getting an error "An error occurred while running the command. Please ask an administrator to check the logs." the logs from the Nextcloud are:
"PHP Error: Attempt to read property "message" on null at /mypath/apps/talked/lib/Command/Record.php#204" and "spreed InvalidArgumentException: Chat command failed [Code: 1]: php /mypath/occ talked:record 'ah6u7siz' 'start'".

My systemd service contains:

I believe I have set this up correctly but I am getting the error. I have searched over the web for the same but I can hardly see a post that covers this issue.
Note: I have gone through this as well - #44

Further, on visiting the link (https://talked.mydomain.com) on the browser, after authentication, I am getting:
{"message":"version: 0.5.0"}
which seems okay.

Looking forward to hearing from you.
