SMS Twilio API errors in command line but no errors in the browser but not sending messages

I had twilio working for some time now, but I wanted to make some changes and save the numbers that are coming with sending errors in a database to avoid sending them again, and somehow, Twilio stopped working. I used it from the browser which shows no errors, but I got these errors when I tried to run the script file from the command line.

Any help is appreciated.
